Poongkyung-Palace(豐慶宮) was the royal palace of Daehan Empire(大韓帝國) which had been constructed at Pyongyang(平壤) from 1902 to 1903. But Poongkyung-Palace is not known to the field of the history of Korean architecture. So, the purpose of this study is to demonstrate the proceeding of construction of the palace by reviewing historical records and documentary literatures. The results of this study are as follows. First, the authorities concerned built Poongkyung-Palace as the royal palace at Pyong-yang to construct two-capital-system(Seoul-Pyongyang) and represent the political and military ideology under instructions from Emperor Gojong(高宗). Second, in spite of the insufficience of fund, material, and manpower etc., the efficient construction organization and the innovation of material conveyance that used railroads was shown at process of the construction. This is regarded as the relevant example that shows the actual state of the last traditional construction managed by the government in early 1900’s. Third, the function and the architectural characteristics of Poongkyung-Palace had changed throughout Russo-Japanese Wars and Japan’s colonial rule of Korea.
