In 1985, Altemose constructed an enormous addition on the west side, which contained the Valley Forge Convention and Exhibition Center and a second hotel tower, which added 160 rooms to the Sheraton. The first structures in the complex were the circular tower of the Sheraton-Valley Forge Hotel, an adjoining twin-screen cinema, and the connected curved executive office tower directly to the east, which opened in September 1973. This led to protests by local union members, during one of which, on June 5, 1972, the construction site was firebombed. The construction was highly controversial, because Altemose chose to use non-union workers. The casino complex originated as a mixed-use development called Valley Forge Plaza, constructed by developer J.
It was constructed on the existing site of the Valley Forge Convention Center and opened on March 31, 2012. Valley Forge Casino Resort is a casino in King of Prussia, Pennsylvania.
