About Centre Square
Centre Square is an office complex located in Center City, Philadelphia, Pennsylvania, United States. The complex consists of two high-rise towers: the 417 feet (127 m) Centre Square I and the 490 feet (150 m) Centre Square II. The concrete towers are the twenty-fourth and fifteenth 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 Towers Perrin is Centre Square's largest tenant. The complex is best known for Claes Oldenburg's sculpture, Clothespin, located in the plaza in front of the building. A fan of contemporary art, developer Jack Wolgin commissioned three art pieces for Philadelphia's percent for art program. The pieces, Oldenburg's Clothespin, Jean Dubuffet's Milord la Chamarre, and a series of banners by Alexander Calder, were noted for helping Philadelphia gain a reputation for the promotion of public art. Centre square was designed by Vincent Kling & Associates and developed by Jack Wolgin.
