Oral History is one of the latest trends in the field of historical study. The Oral history, known as the history of memory or the history written by the memory, has developed nowadays because the milieus of historical memory such as the subject of memory, the group of memory have disappeared by the result of the acceleration of history. The sites of memory is one of the studying field of the oral history started from the French historian, Pierre Nora. Even though many historians around the world are immersed in this subject there is little research results in Korea. In particular, there is no study in the field of Church history. This study is one of the reaction of that kind of research situations. In my opinion, there are many ideas of the sites of memory in the areas of church history. Yanghwajin Foreign Missionary Cemetery ins one of them. As I have been analyzed in this paper, Yanghwajin has the multi-layered historical memory. Firstly, it is the site of memory as the history of our nation, Since the Joseon Dynasty has been founded, this site has been the very important place as the hub for trading, military, foreign affairs during six hundred years. Secondly, it is the site of memory which has been to specify as the National Historical Site, so called Yanghwajin-Jamdubong historical site. Thirdly, it is the site of memory as the place of historical memory in Christian church. There is a foreign missionary cemetery. As the site of memory in church history, Yanghwajin has four historical meanings. Firstly, it has become the site of memory in the field of church history. The Korean Christian churches have restored the foreign cemetery, and has been kept many historical meterials in this place. So, Yanghwajin has become the site of memory. Secondly, we have discovered the multi-layered meaning in the foreign cemetery. There are many differences in Nationality, Denominations, Occupations of the missionaries who were placed in the graves. Thirdly, It has a special historical meaning in terms of restoring of the historical site in the church history. Because of those efforts, this site has become the holy place and the place of memory in Korean Church. Lastly, We should think carefully the fact that the church has been reduced the historical meaning of Yanghwajin by making the site as the only “missionary cemetery,” even though this site has multi-memories in Korean history. In conclusion, we have to restore the multi-historical memories in this place so that Yanghwajin will be offered more rich historical meanings for us.
