History
Tinicum Township has the distinction of being the site of the first recorded European settlement in Pennsylvania. Fort Nya Gothenborg, located on the South River, was settled by colonial Swedes in 1643. It served as capital of the New Sweden colony, under the rule of Royal Governor Johan Björnsson Printz. Governor Printz built his manor house, The Printzhof, on Tinicum Island, from which he administered the colony. The original Lenape called the place Mahtanikunk, meaning "where they catch up with each other". The township is the site of the Philadelphia Lazaretto, the first quarantine hospital in the United States. It and the Printzhof are listed on the National Register of Historic Places.
