Centennial Christian School occupies 2 floors of a 6-story building which was formerly the ICS (International Christian School) building in Yongsan–Dong, on the southwest side of Namsan, just up the hill from Camp Coiner. The facilities are located near Sookmyung Women's Univ. Subway Station on the #4 Blue Line. To come to CCS, you should come out the #5 exit and ride the Mael Bus #02.

It will stop directly in front of the entrance to CCS. If you prefer, you may take a taxi from that subway stop, and ask the driver to take you to the old ICS building. Some maps will show the ICS building and have the full name written out as Gukjae Christian Hakyo.
