高句麗 長安城의 規模와 特徵

The Scale and Characteristics of Chang-An Fortress of Koguryo

Koguryo relocated capital two times. The first capital is located at Jolbon in Lianing prov, second capital is Jian in Jilin prov. Last capital is Pyong-Yang in North Korea. But the age of Pyong-Yang was divided two stages, first stage is north Pyong-Yang organized by Dae-Sung Fortress and An-Hak palace, socalled Do-Sung System(Dual metropolitan system). And second stage is called Jang-An age, and it was included the whole capital in a single organization. I have firm view on the location of palace to Chong-Am-Ri mud-fortress in stead of An-Hak palace. An-Hak palace was a left sided-palace in Koryo dynasty. The structure of Jang-An Fortress was constituted three parts, northern, inside, and middle section. The palace is located in the inside part, md northern castle was special palace with Jo-Bang system. This section made in use of public park. The characteristics of Jang-An fortress is Jo-Bang system, it was the model of Chinese capital system. The Jo-Bang structare was originated in Le-Yang(North Wi), But it was developed in Jang-An age of Koguryo.
