King of Prussia
King of Prussia (also referred to as KOP) is a census-designated place in Upper Merion Township, Montgomery County, Pennsylvania, United States. As of the 2010 census, its population was 19,936. The community took its name in the 18th century from a local tavern named the King of Prussia Inn, which was named after King Frederick the Great of Prussia. Like the rest of Montgomery County, King of Prussia continues to experience rapid development. One of the largest shopping malls in the United States, King of Prussia, is located here. Also located here is the headquarters of the Nuclear Regulatory Commission Region I. King of Prussia is considered to be an edge city of Philadelphia, consisting of large amounts of retail and office space situated at the convergence of four highways.

The Village of Valley Forge is an unincorporated settlement located on the west side of Valley Forge National Historical Park at the confluence of Valley Creek and the Schuylkill River in Pennsylvania, United States. The remaining village is in Schuylkill Township of Chester County, but once spanned Valley Creek into Montgomery County. The name Valley Forge is often used to refer to anywhere in the general vicinity of the park, and many places actually in King of Prussia, Trooper, Oaks, and other nearby communities will use the name, leading to some ambiguity on the actual location of the modern village. There is a partial re-creation of the historic village from the time of the American Revolution that is located next door, and just within the outskirts of the park. Valley Forge is known by travelers in the Philadelphia area as the westbound control city on Interstate 76 (the Schuylkill Expressway), as it is near where I-76 joins the Pennsylvania Turnpike. This remains, despite no exit being designated for Valley Forge, since the previous exit became the off-ramp to Mall Boulevard, serving King of Prussia.
