This paper aims to clarify the transition of the district division plan and the auction process of the residential lots in the Mokpo foreign settlement which is not analyzed so far in detail, through the analyses of the historical materials (official documents and old maps) left in Japan and South Korea. Furthermore, by using the “cadastres” and “cadastral maps” after 1912, it was revealed that the formative process of the typical townscape of the central block which was auctioned off first in 1898 had a close relationship with the changing process of its landholding pattern.
