Historic buildings are history of human kind and a crystal of culture. Therefore, we have a responsibility and obligation to succeed to descendants. Once such heritage is damaged, it is hard to restore its original form. Thus, various attempts to preserve its value and authenticity have been made internationally. Among these, the international preservation tendency of historic building in terms of materials has been given to the preservation of materials as well as the preservation of appearance. In accordance with such trend, Korea also presented an equivalent general principle, and has managed historic buildings with the separate related instruction. The most general method to preserve historic buildings in Korea is a repair work. Since the foundation of Korea, the repair work tendency has been carried out in the principle of phenomenon change and original form maintenance. But, such tendency focuses on the appearance such as style, structure and trimming method, and there is insufficient consideration on the authentic preservation of materials. Accordingly, this study attempts to examine preservation principle and methods in the repair works, and also to investigate the afforestation condition for the restoration work. And, by suggesting preservation method of authentic materials, it aims to prepare the reference for the future repair work.
