The main elements of the project include plans for the restoration of Seyeonjeongji Pavilion and Mireuksa Temple using 3D scan data. Other ongoing research projects include the restoration of ancient buildings such as Hwangnyongsa, Mireuksa and Jeongnimsa Temples, as well as research on heritage resource preservation methods and techniques.
Project to Repair and Restore the Stone Pagoda at Mireuksa Temple Site, Iksan
Stone Pagoda at Mireuksa Temple Site, Iksan
In 1998, based on the results of a structural safety inspection, concerns were raised about the deterioration of the structural safety of the tone Pagoda at Mireuksa Temple Site, Iksan, so the decision was made to carry out a “disassemble and restore” process in 1999. Some two years later, in October 2001, the National Research Institute of Cultural Heritage, in conjunction with Jeollabuk-do, carried out the disassembly, repair, and restoration of the stone pagoda. Although scant precise data regarding the pagoda was available before the repair work was carried out, significant data were collected in the process of dismantling and investigation. Studies are being carried out concerning the repair of stone-made cultural heritage objects, along with diverse academic studies in such areas as architecture, archaeology, art history, and preservation science. The dismantling and excavation of the Stone Pagoda at Mireuksa Temple Site, Iksan has been completed. The work for scientific preservation treatment and maintenance is under way, using the original members as much as possible.
Outline
The Stone Pagoda at Mireuksa Temple Site, Iksan was built in the Baekje Period, during the reign of King Mu (600-641). According to Samguk-yusa (Memorabilia of the Three Kingdoms), on the way to Sajasa Temple, King Mu and his queen saw an apparition of the Maitreya triad. They decided to build a temple on the spot, but it happened to be the site of a pond. Monk Jimyeong helped the king to fill up the pond overnight and accomplish their wish. Mireuksa Temple was completed finally with a layout constituting three areas, each containing a Buddha hall named Geumdang (golden hall) and pagoda.
Thought the pagoda is estimated to have been nine stories originally, it was collapsed before the 17th century and now only six stories remained. In 1915 the Japanese roughly reinforced the broken part with concrete and up until 2001 the pagoda had remained in this deformed shape. The stone pagoda at Mireuk Temple Site is known to be the biggest and oldest (judging by style) stone pagoda extant in Korea. The cross shaped corridor on the first story, central interior column, and structure of the ceiling are characteristic features of ancient stone pagodas.
Cording to the results of a structural safety inspection on 1998, The Cultural Properties Committee decided to dismantle and repair the pagoda for its continued conservation. Jeollabuk-do Administration had started scaffolding construction and begum preparing for dismantling from 1999. In November 2001, the National Research Institute of cultural Heritage began removing the concrete and has been safely dismantling and handling and the separate pieces of the pagoda The work of dismantling and the excavation survey was completed by 2010. The project to dismantle and excavate the Three-story Stone Pagoda of Bulguksa Temple was completed in 2010. The pagoda is currently undergoing repair and conservation treatment work.
Disassembly
Repair and Restoration Process of Stone Pagoda at Mireuksa Temple Site, Iksan
According to the results of a structural safety inspection on 1998, The Cultural Properties Committee decided to dismantle and repair the pagoda for its continued conservation. In preparation for the project, a makeshift hut was set up in 1991 on the temple grounds in Jeollabuk-do and, after October 2001, the National Research Institute of Cultural Heritage took over the project, removing the concrete that had been slapped onto the pagoda for reinforcement purposes and conducting a structural analysis of the disassembled pagoda.
Traditional stonemasons had to break the concrete around the stone pagoda that was cast to enforce the structure in 1915 under Japanese rule. This was in order to remove the stone pagoda from the damaged section. The amount of concrete removed from the site as of 2004 was 185 tons.
A professional grappler had to use a 10ton hoist to carry the stone pagoda and the damaged section safely. The dissembling and transfer of a stone pagoda requires years of experience and advanced skills.
As the stonework was dismantled, the first base of the stone pagoda, and the inner foundation stone, were exposed. From the disassembly of the southwestern section of the stonework it appeared that the newly-found stone statue was in excellent condition, with almost no damage to the face and body. It is assumed that the stone statue was built prior to the stone pagoda.
The stone pagoda’s first base level and inner foundation stone were tilted and displaced, making it imperative to disassemble the structure in order to carry out safe repair and restoration work. In January 2009, during the creation of the cruciform passage, many well-preserved artifacts such as the Sari Urn, which was buried during the reign of King Muwang of Baekje, were excavated.
Measurement
Repair and Restoration Process of Stone Pagoda at Mireuksa Temple Site, Iksan
Before disassembly, the shape of each piece is precisely surveyed with a digital measuring device and the information is recorded as electronic data (three-dimensioned data). Also, in the case of pieces that unavoidably end up in a different position after repair, the difference in position is measured and recorded in order to produce records for comparison and evaluation of the pagoda before and after the restoration project.
The configuration and elevation of all pieces of the pagoda are recorded along with photographs and plans. The survey records of each piece are used to analyze construction techniques and condition and are also used as data for repair and restoration of the pieces.
Measuring points recorded with a digital theodolite Benchmarking scheme Digital solids of all the pieces and their shapes as they appear in the process of dismantling are produced with 3D scanning. Motion simulation and modeling data are produced from the 3D solids to provide basic materials for academic research and structural analysis of the pagoda, as well as investigation of reasons for its collapse.
Excavation
The Stone Pagoda at Mireuksa Temple Site, Iksan was built in the Baekje Period, during the reign of King Mu (600-641). According to Samguk-yusa (Memorabilia of the Three Kingdoms), on the way to Sajasa Temple, King Mu and his queen saw an apparition of the Maitreya triad. They decided to build a temple on the spot, but it happened to be the site of a pond. Monk Jimyeong helped the king to fill up the pond overnight and accomplish their wish. Mireuksa Temple was completed finally with a layout constituting three areas, each containing a Buddha hall named Geumdang (golden hall) and pagoda.
Thought the pagoda is estimated to have been nine stories originally, it was collapsed before the 17th century and now only six stories remained. In 1915 the Japanese roughly reinforced the broken part with concrete and up until 2001 the pagoda had remained in this deformed shape. The stone pagoda at Mireuk Temple Site is known to be the biggest and oldest (judging by style) stone pagoda extant in Korea. The cross shaped corridor on the first story, central interior column, and structure of the ceiling are characteristic features of ancient stone pagodas.

In November 2001, the National Research Institute of cultural Heritage began removing the concrete and has been safely dismantling and handling and the separate pieces of the pagoda The work of dismantling and the excavation survey was completed by 2010. At present, the work of preservation treatment, repair, and maintenance is under way.
Conservation Treatment
Repair and Restoration Process of Stone Pagoda at Mireuksa Temple Site, Iksan
Based on the characteristics of the stone used to construct the stone pagoda, the quarry site, the biological organism colonization and removal trial, and the evaluation of surface pollutants and removal trial, conservation treatment plans were formulated and future conservation management measures established.
The conversation treatment procedure for a section of damaged stone is as follows: cleansing – application of adhesive – application of filler – reinforcement – application of water repellent treatment – color correction. The removal of pollutants is conducted based on the type and degree of damage: both wet and dry methods may be used to reduce the risk of damage.
To reinforce the damaged section, stainless steel, titanium, copper, or resin mortar pins are inserted, based on the condition and reusable parts of the stone.
Damaged fragments are glued together using epoxy resin, which is also inserted as filler into cracks.
The color is carefully restored with acrylic paint after processing the surface ith mineral materials. Apply one to three layers of water repellent depending on the stone's condition.
For parts requiring the restoration of their original shape and form, new stone is processed and added to the damaged section. Various tools are used to match the surface of the newly-processed stone to that of the original, weathered surface.
Sarira Requaries control research
Repair and Restoration Process of Stone Pagoda at Mireuksa Temple Site, Iksan
In the process of dismantling the stone pagoda, 684 artifacts classified into 19 categories at the level of National Treasures, including an urn containing ‘sari’ (Sacred relics of a Buddha), were discovered in a square-shaped case in the center of the first level stone (25cm long x 27cm deep). Among the excavated artifacts, the sarira requary was confirmed to consist of three ‘layers’, i.e., an outer urn, an inner urn, and a glass bottle. An examination of the inscription ‘Geumjesaribongyeonggi’ (“Respectful welcome of a golden urn”) revealed that the stone pagoda was constructed in the “Gihaenyeon” year (639 A.D.).

Research on Restoration and Maintenance of Mireuksa Temple
As a result of the 17-year-long excavation survey of the Mireuksa Temple Site in Iksan (Historic Site), following the survey of the site of the east pagoda in 1974, it was concluded that the temple was the largest one ever built during the Baekje Period. The temple has a unique layout of buildings. There are three Geumdang Halls and three pagodas, each of which is separated with roofed corridors. They are divided into the Eastern Section, Middle Section, and Western Section. We plan to restore the temple based on restoration and archaeological verification research as part of the plan for the preservation of the ancient royal capital of Baekje and to register it as World Cultural Heritage.

Restoration of the Gyeongju Stone Pagodas About the Gyeongju Stone Pagodas and the Project Outline
In accordance with the repair plan established by the Cultural Heritage Committee, based on the results of a precision safety diagnosis conducted in 2001, the National Research Institute of Cultural Heritage has been carrying out repairs on the East and West Three-story Stone Pagodas at Gameunsa Temple Site, Gyeongju Dabotap Pagoda of Bulguksa Temple, Gyeongju, since May 2003, applying also various treatments for long-term preservation of these stone structures.
Cracks were detected in the roof stone of the upper platform of the Three-story Stone Pagoda of Bulguksa Temple in Gyeongju in December 2010. Repair work is currently being carried out by the Gyeongju Stone Heritage Restoration Service.
Preliminary Survey and Record of Present Conditions
Preliminary Survey and Record of Present Conditions of Stone Pagodas
1. Survey of Structural Methods
Surveys have been conducted on the methods of constructing stone pagodas and on the size and location of extant structures. Measurement data are analyzed and used as fundamental data for restoration.
2. 3-Dimensional Configuration Records
We have performed 3-dimensional scanning in order to secure records and basic data for the preservation management of pre-maintenance stone pagodas. Through this 3-dimensional scanning, structural analysis of the present conditions - using techniques such as video, precise measurement, mapping and interpretation - can be conducted, and the conditions of artificial and natural damage can be expressed through simulations.
3. Weather Damage Survey
In order to assess the severity of damage to individual pagodas and formulate future preser-vation management plans, we have created weathering diagrams based on onsite surveys and experimental studies. The weathering diagrams are divided into four principal categories (i.e., surface weathering, surface pollution, biological damage, and repair materials), which are then further divided into sub-categories. Photographic and 3D diagrams have allowed us to determine the overlap between these categories with increasing accuracy. In particular, the analysis of SEM/EDX and ion levels related to surface pollution and biological damage has been used to provide fundamental data for the removal of surface pollutants.
Research on repair and maintenance measures
1. Water Leakage Prevention Research
The East and West Three-story Stone Pagodas at Gameunsa Temple Site, Gyeongju are affected by water leakage, occurring along the joints where roofstone sections meet. Water leakage is affecting also Dabotap of Bulguksa Temple, Gyeongju, in spite of the drainage present along the square parapet encircling the pagoda. We investigated the functionality of the drainage, the causes of water leakage and the damage to the condition of the building stone, and studied action plans to repair leaks and prevent water damage, in order to determine a disassembly and repair methodology.
2. Tenon Restoration Research
Tenons are an important structural component for joining two pieces of wood or stone. Some of the tenons of the three-story stone pagoda in the Gameunsa Temple Site have been lost during a repair. For reconstruction of the pagoda, we surveyed the wedge grooves and analyzed the wedge size and composition in order to make experimental models, as well as studying the connection methods used for the wedges. The results of this study have been reflected in the maintenance work.
3. Repair Strategy Research
Structural risk was recently identified in the West Three-story Stone Pagodas at Gameunsa Temple Site, Gyeongju, whose parts had become extensively displaced, creating gaps. The pagoda was disassembled from its pinnacle to the support stone to the topmost roofstone. The ten disassembled pieces are currently being studied by researchers of the National Research Institute of Cultural Heritage to determine the best restoration strategy. Their joints are examined, and structural calculation is performed through the analysis of the central axis.
4. Conservation Treatment Research
A variety of conservation agents are being used on aging stone structures, ranging from reinforcing agents to improve the resistance of weathered stone components to binding agents applied to adjoining parts that have separated from each other and fillers for plugging holes created from erosion.
As the use and effect of this agent varies depending on the type of stone and the degree of weathering sustained, we have engaged in experimental studies on individual towers to select the most effective restorative agent.
5. Research on stone types for replacement parts
To provide scientific information on the properties of stones used for the construction of historical pagodas and assist restoration specialists with the selection of stones for fabrication of replacement parts, the National Research Institute of Cultural Heritage measures their whole rock magnetic susceptibility rate and performs gamma spectrometer analysis. The type of stone used for the construction of the East and West Three-story Pagodas of the Gameunsa Temple Site , Gyeongju was determined precisely through these procedures. Stones of an identical variety were quarried from a nearby site, for use in the restoration of the two pagodas.
Cultural Property Conservation Treatment
Conservation Treatment of Stone Structures
1. Removal of Surface Pollution Buildups
The leakage at the waterway seams at three-tier stone pagoda Okgaeseok on west and east Gameunsaji are causing the soil to escape and corroding the stone pagoda’s surface. The damage is furthered by winds. There are waterways following the handrails that surround Dabotap Pagoda but foreign objects and weathered waterway is causing the seams to leak. We investigated the functionality of the drainage, the causes of water leakage and the damage to the condition of the building stone, and studied action plans to repair leaks and prevent water damage, in order to determine a disassembly and repair methodology.
2. Emergency Conservation Treatment
During a recent repair and maintenance of the West Three-story Stone Pagodas at Gameunsa Temple Site, Gyeongju structural instability was detected in the eastern pagoda of the same temple site. Its upper base stone and second-level body stone were about to get detached from the rest of the structure. These sections were given an emergency conservation treatment by our team of conservation scientists. A similar emergency intervention has been made to the three-story pagoda of Bulguksa Temple, a portion of whose finial was breaking off.
3. Treatment Recordkeeping
All treatments dispensed for conservation of a cultural heritage structure and building are recorded in detail to eliminate repeat errors in the choice of a treatment regime. The treatment logs, planned to be used for compilation of a conservation treatment manual, are also aimed at facilitating future monitoring activities by providing a complete history of treatments.
4. Weather Monitoring
To gather atmospheric environment data of the Gameunsa Temple Site and Bulguksa Temple, the National Research Institute of Cultural Heritage set up an automatic weather station in both sites, in 2004 and 2006. In Bulguksa, to monitor microenvironmental deviations, an anemo-meter was installed near Seokgatap, and a thermometer and a hygrometer inside Dabotap.
Structural Safety Inspection and Monitoring of Stone Pagodas
1. Structural Safety Inspection and Monitoring of Stone Pagodas
Our conservation science team uses electro-optical distance measuring instruments and crack meters to determine the progress of deterioration of stone pagodas, including displacement, splitting, gaping and damage to stone itself. Stone pagodas are regularly inspected for their integrity to take speedy dispositions upon discovery of signs of deterioration.
2. Continuous Measurement System
Structural distortion started to occur to the three-story stone pagoda of Bulguksa Temple, with its lower base twisted and separated from the rest of the edifice, due to the inner foundation becoming hollow. The pagoda is currently being monitored for structural movements, using a continuous measurement system. The data gathered from this system will be used to determine the precise time-frame for a repair.
3. Structural interpretation through the analysis of the central axis
The structural interpretation of the stone pagoda based on the results of analysis of the central axis is crucial for preventing breakage and splitting caused by structural transformation. Using 3D structural interpretation techniques, our conservation experts work on identifying root causes to structural changes so as to develop a coherent and effective reinforcement strategy to be used during the restoration of the three-story pagoda.

Outline
Hwangnyongsa Temple is mentioned in major ancient historical chronicles such as Samguk sagi (History of the Three Kingdoms) and Memorabilia of the Samguk yusa (Memorabilia of the Three Kingdoms). The temple was originally meant to be a palace. During the construction of what was to become a palace in the eastern section of Wolseong in Gyeongju, in the 14th year of the reign of King Jinheung (553), it was reported that a yellow dragon had appeared at the site. Upon hearing this report, the Silla king ordered that the edifice under construction be turned into a Buddhist temple rather than a palace. The temple was completed in the 30th year of the reign of King Jinheung (569). Five years after its completion, a gigantic Buddha statue over 3m high was cast, and a separate sanctuary (Geumdang) was built in the 6th year of the reign of King Jinpyeong's reign (584) to house it. In the 12th year of Queen Seondeok's reign (643), a nine-story wooden pagoda was erected on the advice of a monk named Jajang to pray for Silla's success in deterring incursions by Japanese pirates. Similarly, Hwangnyongsa Temple was a large temple built over a lengthy period of 93 years, and which was then repaired and rebuilt several times over, surviving until the Goryeo period. However, in the 25th year of the reign of King Gojong of Goryeo, it was completely destroyed during a Mongol invasion, so today only the site remains. The wide, bare site of Hwangnyongsa Temple remains, but an 8-year-long excavation survey conducted from 1976 revealed the full scale of the magnificent temple built in the Silla period. The more than 40,000 artifacts unearthed from the site becameinvaluable materials for the study of that period. Thanks to the results of this excavation, the Hwangnyongsa Temple was registered as part of the Gyeongju Historic Area, which was itself registered as a World Heritage Site in December 2000.
The Hwangnyongsa Temple Area was purchased as part of the Gyeongju Tourism Comprehensive Development Plan, which enabled extensive excavation surveys and historic site maintenance to be conducted there. The historic site maintenance team, using the results of the excavation as the basis of its work, arranged and embanked the foundation stones and planted grass, as well as engaging in protective measures to preserve the remains of the structures. They also installed information boards and wooden steps for visitors
Subsequently, the city of Gyeongju decided to restore Hwangnyongsa to its original appearance, and requested the National Research Institute of Cultural Heritage to draw up a restoration master plan and host an international conference on the topic. After a feasibility study, the master plan was completed in 2007

Collective Suggestions
Hwangnyongsa Temple, whose construction was begun in 553 and completed in 645, is an important historical heritage site which demonstrates the essence of Silla Buddhist culture. The speakers and debaters that attended the Hwangnyongsa Temple International Academic Conference held in Gyeongju on the 28tth and 29th of April 2006 gave the following recommendations.
One : Value and Meaning
The restoration of Hwangnyongsa Temple is worth reviewing from the historical, educational and tourism perspectives, and will be a source of pride for both the people of Gyeongju and Korea as a whole.
Two : Direction of the Reconstruction Plan
The reconstruction of Hwangnyongsa Temple must be pursued in a direction that respects its inherent status as a cultural heritage.
Three : Necessity of Research
There needs to be a sufficient preliminary accumulation of in-depth studies in various fields for the reconstruction of Hwangnyongsa Temple to proceed smoothly.
Four : Methodology of Reconstruction
The reconstruction of Hwangnyongsa Temple must be cautiously promoted to meet with the special historical and cultural characteristics of Gyeongju while complying fully with international preservation standards.
Five : Consensus
Opinions must be widely collected on the reconstruction of Hwangnyongsa Temple, not just from related scholars and experts but also from the local community and civil groups.
Hwangnyongsa Temple Restoration and Maintenance Research
Our objective is to create a comprehensive restoration and maintenance plan for Hwangnyongsa Temple for the promotion of leading reconstruction projects in Gyeongju, of which the restoration of Hwangnyongsa Temple is a part. The comprehensive plan for the restoration and maintenance of Hwangnyongsa Temple will also present a new direction based on multiple fields for the restoration of ancient buildings. This is indispensible to the development of rational validity and public consensus on the promotion of restoration work. It is hoped that these various studies will increase the success of academic research in other related fields. We have been promoting preliminary restoration studies and basic studies in such fields as history, archaeology, art, Buddhism, urbanology, landscaping and historical architecture relating to historical work and the restoration of Hwangnyongsa Temple, and have published a 9-volume research series on Hwangnyongsa Temple. Our current work included the goal of creating a comprehensive restoration plan for Hwangnyongsa Temple by March 2012.

Master Plan for Maintenance of the Jeongnimsa Temple Site
The Jeongnimsa Temple Site (Historical Site) was the location of a Sabi-period Baekje Buddhist temple, now in downtown Buyeo. Jeongnimsa Temple was destroyed around the year 660 by the army of Tang General Su Ding Fang, and the area was known only as a Baekje-related historical site where a pagoda named Pyeongjaetap, or Su Ding Fang-tap, was located. The former existence of the temple was not discovered till 1917 when the name Jeongnimsa was found inscribed on a roof tile, identifying the temple as one that had closed down in the Goryeo Dynasty. The Five-story Stone Pagoda (National Treasure) is located above the central line south of the temple area, while Yeondongni Seated Stone Buddha (National Treasure) is situated in the hall area.

Outline
Following the first excavation surveys of the Jeongnimsa Temple Area by Japanese scholars during the Japanese Imperial Period, the temple site was used as a Baekje pagoda park. As such, the full story of the temple complex was not revealed until the 1979-80 excavation survey by Chungnam University. The results of the survey led to the ‘earth-sheltering’ and maintenance of Jeongnimsa temple and to the erection of a protective canopy over the stone Buddha in the main hall area. Recently, the Jeongnimsa Temple Area Museum was opened to provide information and tourism materials about the historic features of the site. Maintenance work on the Jeongnimsa Temple Area began as part of a restoration and maintenance project with historical and cultural dimensions, and the National Research Institute of Cultural Heritage’s Gameunsa Temple Site, Gyeongju Restoration and Maintenance Team put the master plan for the site into effect in October 2005, and completed it in December 2006.
Plan Objective
- Reproduction of Baekje Architectural Culture
- Redevelopment of the Tourism Environment through Effective Maintenance
Plan Direction
- Effective Maintenance Plans for Redevelopment of the Tourism Environment
- Basic Planning for Social and Economic Feasibility Studies related to the Promotion of the Restoration and Maintenance Projects at the Jeongnimsa Temple Area
Basic Plan
- Area Reestablishment : Reconstruction and specialization of the Jeongnimsa Temple Area domain (restoration and maintenance) and the museum domain; domain planning for a practical application space between the Jeongnimsa Temple Area and the existing museum.
- Maintenance of the Tile Kiln Site : Construction of a Protective Canopy after Maintenance of the Baekje Tile Kiln Site
- Spatial Planning for Buyeo Residents : Expansion of Rest Facilities and Spaces for Commemorative Events

- Improvement of Landscaping: Package Plans for Each Area and Planning for Landscaping
Basic Plan for Comprehensive Maintenance of the Gameunsa Temple Site, Gyeongju
The Gameunsa Temple Site, Gyeongju (Historic Site) was built as a patriotic temple during the United Silla period; the east and west three-story stone pagodas remain in good condition. It is a valuable cultural heritage asset where traces of the foundation stones and stereobates of the buildings have survived to the present day. Previous excavations of the Gameunsa Temple Site, Gyeongju include a 1959 survey by the National Museum of Korea and a 1979-80 survey by the National Research Institute of Cultural Heritage, reports on which where published in 1961 and 1997, respectively. The Gameunsa Temple Area cannot simply be left as an abandoned temple buried by the past but must be maintained as an active historic site that can connect with modern-day visitors.
The site is also in close proximity to the Underwater Tomb of King Munmu (Historic Site) in the East Sea, which is a symbol of that king’s passionate patriotism: As such, the sites may be used in conjunction to promote and encourage patriotism in local citizens and people from all over the country. This project, following the request by Gyeongju City in December 2006 for enterprises to act as proxies for the Master Plan for Comprehensive Maintenance of the Gameunsa Temple Site, Gyeongju, put the master plan into effect as part of the National Research Institute of Cultural Heritage: Gameunsa Temple Site, Gyeongju restoration and maintenance team, and brought it to completion in December 2007.
