The Taipei Arena is an important indoor facility within the city of Taipei’s overall exercise facility construction plan. The building is divided into the main hall and subsidiary arena. The main hall is comprised of 2 underground levels and 5 reinforced concrete levels above ground, covering an area of approximately 90,900 square meters. The interior floor of the main hall is 76m long and 41.5m wide and about 60m X 29.5m when all retractable seats are fully extended. When needed, the center floor can be completely frozen and become a standard indoor arena for sports or other events held on ice. The arena can be used for a variety of purposes based on need. Because of this, the arena was able to host top of the line racing competitions held by SportAccord (International Sports Federations) and is also in hot demand by both domestic and international arts groups who compete to rent it out for a variety of shows.
