Jangchungdan is located at the skirt of Namsan near Namsomundongcheon, so the buildings are arranged with many podiums. The steps for people to go up and down such podiums are placed around the buildings. The Western-style constructional methods and materials introduced by the opening of ports were used for a variety of Jangchungdan buildings with differentiated levels of podiums, for Jangchungdan memorial ceremonies, and other building materials were also installed along with the changes in clothes and lifestyles. Although Dansa was constructed in the Chinese style, it reflected the shrine plane used in Joseon Dynasty, which in turn is thought to reflect Gubonsincham, the basic concept of Gwangmu Reform, as in the case of Jangchungdan memorial ceremonies.

The purpose of this study was to determine changes in neighborhoods due to the development of residential districts around Jangchungdan(獎忠壇) altar in Seoul from the 1920s to the 1930s. In the Joseon Dynasty, this area was a protected and sacred area to honor the spirit. The reputation of the area, however, turned into the place to play and take a rest and neighborhoods around Jangchungdan altar were developed as high-grade residential districts with the impression of suburbs during the Japanese colonial period. Residential districts were formed with the destruction of the Hanyang City Wall and the privatization of nation-owned forest, which were physical and symbolic boundaries of Seoul in the Joseon Dynasty.
