The community took its name in the 18th century from a local tavern named "The King of Prussia Inn", which was named for Frederick II, King of Prussia. King of Prussia like the rest of Montgomery County, continues to experience rapid development. The King of Prussia Mall, the largest shopping mall in the United States, is located here. King of Prussia comprises two malls, The Court and The Plaza, which are connected by a short covered crosswalk. King of Prussia has become a highly developed community due to the construction of the nation's largest shopping mall, thousands of homes, various hotels and skyrises, strip malls, restaurants, freeways, convention center, and much more. However, homes and farmsteads older than 200 years still dot the rolling countryside, and much is being done to protect them.
