The Centrium (Chinese: 中央廣場) is a skyscraper located in the Central district of Hong Kong. The tower rises 41 floors and 189 metres (620 ft) in height. The building was completed in 2001. It was designed by architectural firm DP Architects, and was developed by the Sino Group Limited. The Centrium, which stands as the 75th-tallest building in Hong Kong, is composed almost entirely of commercial office space; the lowermost floors are used for retailing. It has a total floor area of 23,775 square metres (255,900 sq ft). A spire was added to the building in 2002, one year after its initial completion; the spire lights up in various colors at night.
