In the 1960s, Wolgin began development of a two-tower high-rise complex in the West Market Street neighborhood of Philadelphia.

[1] The Metropolitan Life Insurance Company (MetLife) had an ownership stake in the complex ever since Centre Square was constructed and in 1992 became the sole owner.

[6][7] With the acquisition of Centre Square, HRPT Properties Trust (now called Equity Commonwealth) began an improvement and renovation plan for the complex.

Architectural firm Daroff Design Inc.'s plans included cleaning the structures and a redesign of parts of the atrium and the plaza in front of the building.

[6][8] Located just across 15th Street west of Philadelphia City Hall, Centre Square was designed by Vincent Kling & Associates.

[4] The 40-story west tower, Centre Square II, located at the corner of Market and 16th Streets, stands 490 feet (150 m) tall.

Until the company left in the mid-1980s, Arco Chemical Co., whose headquarters was in Centre Square, had a large collection of contemporary art displayed throughout the complex.

[13] A fan and collector of contemporary art, developer Jack Wolgin had three pieces commissioned to fulfill the ordinance.

[3] The most famous piece is Claes Oldenburg's 45 feet (14 m) Cor-Ten and stainless steel sculpture, Clothespin.

After pressure from the Philadelphia Redevelopment Authority art program to search for the banners, they were discovered in a storeroom in the early 2000s.

Made by Miriam Singer and Emilie Ledieu, the mural is intended to represent the geographies of the people who pass through the plaza and is expected to be completed in November 2011.

[8] It left Centre Square for its new headquarters in the Comcast Center despite attempts by HRPT Properties Trust to convince them to stay.

[21] The company makes 32,000-square-foot (3,000 m2)[22] in the west tower its headquarters despite moving 400 employees, including its top management, outside of Philadelphia and into Radnor Township, Pennsylvania in 2007.
