The purpose of this study is to identify the characteristics of monuments in the Seoul Foreigners′ cemetery at Yanghwajin, a place where many prominent Christian missionaries and other Christians have been buried near Choltusan. In considering the characteristics of gravestone details, the researcher has divided the details into 4 analysis categories: forms, symbols, epitaphs, and materials. For this research, 281 monuments were selected including 68 of missionaries, 26 of U. S. Army Soldiers, and 13 of teachers. The analysis revealed that there were 26 types of monuments. This includes simple and standardized types like the tablet, headstone, marker, and monolith. These were used more often than other shaped types such as the Cross, obelisk, sculpture, etc. Standardized types made in Korea have been preferred after the 1950s even though the beauty of the gravestones has been degraded. Symbolical decorations related to religious, social, professional or military emblems were also introduced to strengthen their symbolical objectives. Among them, fie Cross was the most predominant Christian symbol and emblem. The families wanted to inscribe epitaphs, the greater part of which originated from the Bible, poems, idioms related to tribute, rest, supplications to deity, love, achievement, to express human sentiment and religious faith. When using materials for making monuments, monument makers have mostly used stone because of its durability. Until the 1950s, various stones had been used to make monuments, for most marble and granite were brought from foreign countries. These were very different from the Korean white marble stone used for many monuments. After the 1950s, the source of stone has been limited to Korean stone, for Korean could make stone monuments that foreigners were agreeable. Especially, a black marble stone called "O-Suk" which means black stone, has been used as a main material. The study identified the following characteristics of monument details in the Seoul foreigners′ cemetery at Yanghwajin. First, Christianity has been applied as the main concept, while symbolizing the homogeneity of religious, family, social, professional or military groups by having the symbolic form, symbol, and epitaph in common. Second, monuments made after the 1950s have been standardized into unattractive and monotonous forms by the limited materials, and so the beauty of the monuments has been degraded.

World state of the arts of the conservation of stone monuments is reviewed and the modern conservation program based on conservation science is proposed for the scientific conservation of stone monuments in Korea. The conservation program suggests that the site environment diagnosis, decay diagnosis, petrophysical property analysis, and conservation experiment should always be carefully studied before conservation treatment. It is an up-to-date widely accepted concept in the world of stone conservation science. Our urgent national tasks that should be accomplished for the scientific conservation of stone monuments in Korea are proposed in the following: 1) The stone monument conservation projects should be planned in accordance with 'Conservation Concept of Stone Cultural Properties' and executed in accordance with the proposed 'Conservation Program for Stone Cultural Property' based on conservation science. 2) It is proposed that 'National Institute of Conservation Science for Cultural Properties' be established for systematic conservation research on the tangible cultural properties. 3) The conservation projects of stone monuments should be executed under the control of stone conservation specialist for their quality control. 4) Special national budget should be prepared for quick development of researches on conservation science in Korea.

Culture has long been associated with and advanced by stone as observed in prehistoric dolmen, menhir, megalith monuments, memo-rial stones, and others. The closs association of monuments is seen even in an earlist form of culture and is witnessed to evolve with human history. Korea, with its large quality granite repository, has been active with granite-based monuments in various forms of towers, bridges, and larterns. These stone structures are so abundant throughout Korea that Korea has been called the country of stone tower in Asia. With this historical background, we survey these Korean memorial stone and monuments, found at roadsides, momerial buildings, village entrances, scenic places, schools, sermon halls, public pleasure ground, and other common places. Based on installation orientation, location, and size, a particular emphasis is on the structural value, meaning, beauty, and function of these momnuments coupled with trees, shrubs, water and appropriative landscapes.

There are many stone monuments which are weathered by natural or artificial factors in Korea. The partly weathering in stone could accelerate the rate of weathering, so it is demanded to keep them from the further weathering. Consolidation is evaluated as one of the efficient treatments which have a good effectiveness in stone monuments. But following the former researches, the effectiveness of consolidation could be different, related to the kinds of stone or consolidants. Therefore, in this study, the change of properties was monitored in the long term for the exact evaluation of the stability of the consolidated stone. It is estimated that the pore structure of consolidated stone was filled by consolidant, according to the measurements of ultrasonic velocity, and the digital image analysis of the sample was shown that the color property of stone surface has varied during the curing.

The investigation has been made on the rocks consisting the pagoda(12), Buddhist Statues(9) Buldaejwa and cakra(2, rewpectively), stele(5), and Flagpole wupport and stupa(6) which are stood in Weonju city, Weonju-gun, Hwoengseong-gun and Hongcheon-gun, Kangweondo. These rock-monuments range mostly in age from late Shilla Kingdom to middle Korye Kingdom. The geology around this region is mainly composed of Precambrian metamorphic rocks and mesozoic granitic rocks. The granitic rocks are largely divided into Jurassic and cretaceous ones which are slightly different in rock phase. The main rock phase consisting the monumentsare are coarse biotite granite with minor amount of hornblende in Jurassic age. Variation in rock phase is abserved even in part of the stone used in the monuments. Inclusions composed of biotite and hornblende, porphyritic texture with microcline phenocryst, igneous lineation and exfoliation according to weathering are observable in all rocks in these monuments. In the case of stele whose a body and a capstone is remained, one is composed of black slate and the other white limestone. But the turtle shaped pedestal is constituted of coarse biotite granite. These stone-monuments are strongly weathered and exfoliated out about 1∼2mm.In case of exfoliated weathering along igneous lineation, some are taken off about 3∼5mm thick. In some monuments, the degree of weathering is somewhat different according to position, grade of sculpture, and biological activity.

Stone has been one of the most intensely studied materials in conservation. Understanding the deterioration of stone needs various knowledge in different mineralogical and physical characteristics and its weathering response under different climate and environment. The alteration and weathering of stone is affected by natural or artificial elements whether they are physical, chemical or biological damaging factors. It can be said that the bio deterioration of stone is coupled with every environmental factors, which induce decomposition of stone structure, either directly or indirectly as a form of catalysis. Many elements contribute to the deterioration of stone monuments and other objects of cultural value such as pagoda, stature of Buddha, etc. This report concentrates on the action of biodeteriorative factorsincluding bacteria, algae and higher plants. Preventive and remedial methods and a selection of chemical treatments are also described.

Most stone monuments in Korea are made from the granitoids found extensively throughout the nation. To identify the provenance of the stone materials, this study carried out comprehensive analyses of the occurrence, physical properties, mineralogy, and chemical composition of Stupa for National Preceptor Wongong at Geodonsa Temple and Five-story Pagoda at Cheonsusa Temple, both located in the Gangwon region. Their features were compared with those of granite from Wonju City near the sites of the two monuments. Stupa for National Preceptor Wongong is composed purely of two-mica granite, whereas Five-story Pagoda was made from both two-mica and biotite granites. The occurrence and magnetic susceptibility of the two granite monuments generally coincide with those of granite from Wonju. When selecting materials for the restoration of stone monuments, it is deemed necessary to carry out a field survey on granite in areas adjacent to the locations of the stone monuments subject to restoration.

The Shilla Stone Monument in Jungseongri was found during the road-construction in Pohang. It has approximately two hundreds of letters inscribed on the surface of one side, and it is estimated to be older than Shilla Stone Monument in Naengsuri which had been known for the oldest stele in Shilla Period. This monument is made of fine to medium-grained biotite granite, while the Shilla Stone Monument in Naengsuri is made of fine-grained granodioritic porphyry bearing feldspar and amphibole phenocrysts. Both rock types of the monuments are interpreted to be cognate with biotite granite in Shinkwangmyeon, and with granodioritic porphyry in Gigyemyeon. They are characterized by xenolith and miarolitic cavity. Damage aspects in both monuments are discoloring, cracking and breaking. These damages do not cause structural instability of the monuments, but attenuate aesthetic value. Black and brown discoloring contaminants on the surface of the Jungseongri Monument contain a high amount of manganese and iron. As a result of ultrasonic test, both monuments were evaluated to be medium-weathered (MW), although the velocity of the Shilla Monument in Jungseongri was slightly lower than the Shilla Monument in Naengsuri. This is because the Monument in Juengseongri had been exposed to outdoor environment for long time until the discovery. It is necessary for Shilla Monuments to be protected by appropriately environmental control and management.

Stone-monuments, distributed in this area, have been investigated and studied in geological and conservational points of view. They are seemed to have been built from the Shilla to Koryeo Kingdoms, although more systematic studies are needed. The used rocks in these monuments are mainly biotite granite of Jurassic age. They are strongly weathered and partly exfoliated along igneous lineation about 1-2 mm(maximum up to 5 mm). They are mainly effected by chemical weathering to be selectively dissolved and by various kind of moss. For conservation, it must be scientifically considered based on characteristics and kind of rock phase, factors on weathering process, situation and protection.

Blackening on stone monuments is serious problem, because it is not only aesthetically unattractive, but also an important process in stone deterioration. Black surface layers contain often a large amounts of iron compound. Therefore it is assumed that besides another elements the iron have influence on blackening of surface. After the samples of black surface layers were collected from the stone monuments (Museumsinsel) in Berlin, Germany, especially in this study has been used Mossbauer spectroscopy in order to determine the valence and chemical composition of iron. Mineralogical and chemical analyses were carried out X-ray diffractormetry and X-ray fluorescence method on the black surface layer's samples and original stone samples. The origin of Iron compound in the black surface provides the important clue for the conservation work of stone monuments, like removing of black surface. To find it, black surface layer on white sandstone -it contains very small amount of iron compound- was compared with that on the red sandstone (Fe contains very small amount of iron compound- was compared with that on the red sandstone (Fe abundant). As a results, it is assumed that the iron in black layer on white sandstone is originated mainly from a surrounding environmental material and for the iron in black layer on the red sandstone is responsible the original stone. Even if black surface layer was removed from the red sandstone, some other conservation method should be studied beyond removing of black surface layer, because the iron can move continuously from the inner zone of original stone to surface area.
