Centre Square is an office complex in Center City Philadelphia, Pennsylvania. The complex consists of two concrete high-rise towers: the 417 feet (127 m) Centre Square I, also known as Centre Square East, and the 490 feet (150 m) Centre Square II (Centre Square West) represent the 24th and 15th-tallest buildings in Philadelphia, respectively. Designed by Vincent Kling & Associates in the 1960s, Centre Square opened in 1973. The complex is credited with shifting Philadelphia's downtown office district from South Broad Street to West Market Street. A tenant since 1975, management consulting firm Willis Towers Watson is Centre Square's largest tenant.
The complex is best known for Claes Oldenburg's sculpture, Clothespin, in the plaza in front of the building. A fan of contemporary art, developer Jack Wolgin commissioned three works under Philadelphia's percent for art program: Clothespin, Jean Dubuffet's Milord la Chamarre, and a series of banners by Alexander Calder. The works helped Philadelphia gain a reputation for promoting public art.
