According to the results of the excavation of Asuka-dera Temple, the temple had a garan layout in which a pagoda stood at the center of the area surrounded by roofed corridors, and surrounding it were three main halls (central main hall, east main hall, and west main hall); such construction follows the Goguryeo-style and is believed to have originated in the Sangoin layout of China.
飛鳥寺の発掘調査結果によると、回廊で囲まれた区画の中央に仏塔が建ち、これを中金堂・東金堂・西金堂の三金堂で囲む伽藍配置で、高句麗の形式を踏襲しており、中国の三合院配置に起源があると考えられる。
