Tapgol Park and Jongno 3-ga are representative male elderly's spaces. Although it is surrounded by various urban spaces such as Insa-dong, Ikseon-dong, Youth Street, and Nakwon Shopping Center, Jewelry Wholesale and Retail Street the area is full of male elderly. This place, which can only accommodate a narrow class of low-income male seniors, has become an increasingly monotonous space and has lost publicity. For other classes, this has become a dead space, or a place to avoid.

Tapgol Park has experienced many changes over a long period of time, in boundaries and green tissue. Currently, there is a mass fence that cuts off the inside and outside, three of the doors on all sides are closed, and the green area organization and roads are isolated and torn apart into debris. By regulating the behavior of the elderly and establishing continuity around the monuments, this place has become a place to look around and go out, not a place to stay.

In order for the male elderly's ecosystem to continue, and for Tapgol Park to become a valid place for urban people, changes are needed here. The goal is to create a space where different classes can be exposed to each other. By restoring the cross axes of Tapgol Park, the memory of the land is symbolically revealed. These extend the existing roads into the park and at the same time become a guideline for the system of underground buildings. In the basement, an archive is planted to store various memories of Tapgol Park. It is hoped that Tapgol Park will operate as a city park and a large buffer zone connecting Jongno in the south with male elderly's space in the north.
