Jamsil Students' Gymnasium

The Jamsil Students' Gymnasium The Seoul Metropolitan Office of Education owns the building, which sits near the Olympic-ro thoroughfare. It has served as a home court for the Korean Basketball League (KBL) since the 2004–2005 season, when the Seoul SK Knights moved in from the adjacent indoor arena. That move brought a steady stream of games to a hall that originally opened for boxing at the 1988 Summer Olympics and the 1986 Asian Games. The parquet floor that served the early games was replaced with a synthetic surface for volleyball and rhythmic gymnastics during the 1992 Olympic cycle, and the venue has since adapted to the demands of both basketball and handball.

It has hosted the V-League All-Star Game, the FIVB Volleyball Women's Challenger Cup, and the annual KBL Rookie Draft, while also serving as a nominal home for the Seoul City Hall Women's Handball Team and the Doosan Handball Team. The complex is slated for redevelopment ahead of a potential 2036 Olympic bid, and the gymnasium will be relocated and rebuilt to include swimming and diving pools alongside the basketball court. Some upgrades arrived earlier: table seats were added in the 2015–2016 period, and the hall played host to the finals of the Tving Starleague in 2012, an event that drew over 12,000 spectators.
