The CCTV Headquarters is a 234 m (768 ft), 44-storey skyscraper in the Beijing Central Business District (CBD) and serves as headquarters for China Central Television (CCTV). The main building is not a traditional tower, but a loop of six horizontal and vertical sections covering 473,000 m (1,552,000 ft) of floor space, creating an irregular grid on the building’s facade with an open center. The CCTV building was part of a media park intended to form a landscape of public entertainment, outdoor filming areas, and production studios as an extension of the central green axis of the CBD.
