Clothespin by Claes Oldenburg - oversized public sculpture at Centre Square

Clothespin is a 45‑foot Cor‑Ten steel sculpture by Claes Oldenburg installed in 1976 in Centre Square near 15th and Market Streets and is a prominent example of late‑20th‑century public art in Philadelphia. The sculpture reinterprets a common household object at monumental scale and has been a distinctive visual landmark in the city's downtown plaza. It is sited opposite City Hall and has been part of ongoing public art discussions about urban sculpture and place.
