King of Prussia is a census-designated place considered to be the edge of Philadelphia. The area was named after the King of Prussia Inn which was originally built as a cottage in 1719 by a Quaker family. It was converted into an inn in 1769 and had steady business as it was about a day's journey from Philadelphia. It was almost destroyed when the state wanted to expand US Route 202. Thankfully, the tragedy was avoided due to the advocating of preservationists.

We are happy to serve King of Prussia, zip code 19406, and the surrounding areas.
