The Heydar Aliyev Center is a 57,500 m building complex in Baku, Azerbaijan designed by Iraqi-British architect Zaha Hadid and noted for its distinctive architecture and flowing, curved style that eschews sharp angles. The center is named for Heydar Aliyev, the leader of Soviet-era Azerbaijan from 1969 to 1982, and president of Azerbaijan from October 1993 to October 2003.
