Muckinipattis Creek or Muckinipates Creek is a 5.4-mile-long (8.7 km) creek which runs through Delaware County, Pennsylvania and enters Darby Creek just prior to the Delaware River. The creek is believed to begin with two branches, one in Springfield Township and the other on the southwest corner of Springfield Road and Bishop Avenue. The Muckinipattis then proceeds past the Primos-Secane swim club in Upper Darby Township. Further downstream it flows under the former A&P parking lot in Secane before forming the border of Darby and Ridley townships. It empties into Darby Creek between the shores of Montgomery Park in the borough of Folcroft and the historic Morton Morton House in Norwood. The name Muckinipates derives from a Lenape word meaning 'deep running water'. The Otter and Turtle tribes within the Lenni Lenape nation lived and hunted along the creek, and had a small village on what today is Montgomery Park in Folcroft.The Old Mill, or Old Mill Dam (known by locals as 'The Falls'), which today sits at the junction of Delmar Drive in Folcroft, South Avenue in Glenolden, and East Amosland in Norwood was built in 1775 by Thomas Shipley. The gristmill was popular among grain farmers from as far away as Delaware and New Jersey, who would operate barges called "one stickers" up the Muckinipattis to have their goods processed. The mill was at one time owned by John Morton, grandson of Morton Mortensen, and the deciding vote on the Declaration of Independence.The mill was sold and re-purposed a number of times. It was a bobbin factory when it finally burned down in February 1899. The confluence of Muckinipattis Creek with Darby Creek is next to the John Heinz National Wildlife Refuge at Tinicum.

The Philadelphia Lazaretto was the first quarantine hospital in the United States, built in 1799, in Tinicum Township, Delaware County, Pennsylvania.

The Printzhof, located in Governor Printz Park in Essington, Pennsylvania, was the home of Johan Björnsson Printz, governor of New Sweden. In 1643, Johan Printz moved his capital from Fort Christina (located in what is now Wilmington, Delaware) to Tinicum Island. At that time Fort Gothenburg was established in addition to Printz's dwelling and headquarters. Two years later a fire swept over the newly established settlement. The Printzhof was reconstructed more solidly and lavishly. The two-story log structure contained lumber sent from Sweden, glass windows and lavish draperies.Johan Björnsson Printz, his wife and younger children returned to Sweden during 1653. The Dutch West India Company subsequently captured the Swedish colony in 1655. Armegott Printz, the eldest daughter of Governor Printz, had married his successor, Lt. Johan Papegoja. She remained at The Printzhof even after the Dutch conquest. During 1662, she sold the estate for a partial down payment with the remainder due when she reached The Netherlands. When payment was refused, she returned to reclaim possession of her property. Ten years later in 1672, the Governor and Council ruled Armegott Printz should be in possession of the property. She subsequently sold the estate a second time and returned to Sweden where she died on November 25, 1695 at Läckö Castle.Today, the Printzhof's stone foundations are the only remains of the settlement. The Printzhof site is located near the intersection of Taylor Avenue and Second Street in Essington, Pennsylvania. The site was declared a National Historic Landmark in 1961.
