This study tries to find out the commonalities and differences during the 20th century between the characteristics of Hanyang Sijeon revealed in previous studies by identifying the location of the Sijeon (market zones) installed in Namdaega, Gaeseong, the relationship between lots and streets, and the characteristics of the building arrangements. As a result, the integrated structure of the front and the doga, the market structures of Gaeseong, which have been passed down since the Goryeo Dynasty, influenced and developed those of Hanyang. In particular, additional furnaces were installed in the front, which led to the birth of Pimat-gil alleys. In determining the size of urban space, the scale of Gaeseong City was also applied to Hanyang, which became the basis for determining lots and roads around the market zones.
