This thesis is a study to Haengnang(行廊, a series of buildings) of Sijeon(市廛, licensed markets), which was built along with palaces, Jongmyo(宗廟) and roads in order to establish Hanyang(漢陽) as the capital of Joseon (朝鮮). Sijeon, built on Jongno and Namdaemun-ro, the main roads in Hanyang, created two-row lands on both sides of the road, and formed Pimat-gil as an inner road between the Jeonbang and Doga. The formation of the city proceeded along with the maintenance of the water path, and the situation of the water path parallel to the flow of Sijeon was achieved. The Sijeon building was a spatial structure managed by independent rooms as a result of reflecting the unique operation method of Sijeon. The Sijeon of Hanyang had an impact on the formation of land, architecture, roads, and waterways, and acted as a major factor in determining the urban spatial structure of Hanyang City.
