The Taipei Mosque, the site of the Taiwan Muslim Association, was named as a historic site in Taipei in 1999. It is now the largest and most famous temple in Taipei. The green domed worship hall, with a crescent moon hanging high on both sides of the top, is a tradition of summoning the cylindrical ring of the worship building. Beyond Mahjor Day, it is used as a classroom to teach Muslims how to learn religion, read the Koran and learn Arabic.
