The  King of Prussia Inn was originally constructed as a cottage in 1719 by Welsh Quakers. The cottage was converted to an inn in 1769 and did a steady business in colonial times as it was approximately a day's travel by horse from Philadelphia. Settlers headed west to Ohio would sleep at the inn on their first night on the road. General George Washington  visited the tavern. The inn was moved with the expansion of U.S. Route 202,
