Pennsylvania Square Mall (commonly known as Penn Square)is a two-story, 1,100,000-square-foot (100,000 m2) upscale regional shopping mall with a 10-screen AMC Theatre in Oklahoma City, Oklahoma, United States. It is located at the intersection of Pennsylvania Avenue and NW Expressway, near I-44.
The center was originally built as an outdoor shopping center in 1960 with anchors John A. Brown and Montgomery Ward. Other major attractions included Rothschild's clothing store, Val Gene's Cafeteria and coffee shop and Extension One women's clothing store. After the opening of regional enclosed malls such as Quail Springs Mall and Crossroads Mall, the center was enclosed in 1982 and renovated in 1988 to include a second level and food court at a cost of $100 million. A multi-story parking structure was added and the mall further expanded in 1995, and the mall renovated once again in 2000. The mall's six entrances were rebuilt in 2007 and 2008. Hotels, strip malls, and "big box" retail stores, were built around the perimeter by other owners, the largest being Belle-Isle Station in 1999, a 45-acre (180,000 m2) development at the site of the former Belle Isle lake and power plant, that includes a Wal-Mart Supercenter.
