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 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.
