The shape of an inverted diamond, the Hong Kong Coliseum is the second biggest indoor facility in Hong Kong. It’s a popular destination to host concerts, performances as well as sports events.  Designed by the government’s Architectural Services Department, the Hong Kong Coliseum features a column-free interior that can seat up to 12,500 audiences.  The 1,680-square-meter space also offers an unobstructed view of the centrally located stage from all angles.  The concrete frame of the structure is reinforced to withstand more pressure than a normal concrete building – hence, allowing the flexibility to build various types of platforms and stages. It was remodeled to accommodate a 25-meter-long swimming pool once for an international competition in 1999. In addition to the main arena, the building also houses conference rooms and open areas for conventions.  The story of the Hong Kong Coliseum began when the government decided to build the first international-standard indoor coliseum in Hong Kong in the 1960s.  It wasn’t until 1977 that the construction began in Hung Hom. It was officiated in 1983 by the then-Hong Kong governor Sir Edward Youde. The opening ceremony was live-broadcasted on televisions.  The Hong Kong Coliseum was the biggest indoor venue before the AsiaExpo was open in 2005.
