About this property
Fort Mifflin , originally called Fort Island Battery and also known as Mud Island Fort , was commissioned in 1771 and sits on Mud Island (or Deep Water Island) on the Delaware River below Philadelphia, Pennsylvania near Philadelphia International Airport. During the American Revolutionary War, the British Army bombarded and captured the fort as part of their conquest of Philadelphia in autumn 1777. In 1795, the fort was renamed for Thomas Mifflin, a Continental Army officer and the first post-independence Pennsylvania governor. The U.S. Army began rebuilding the fort in 1794, and continued to garrison and build on the site into the 19th century. Fort Mifflin housed prisoners during the American Civil War.
Location
Federal Designation
The National Register of Historic Places, administered by the National Park Service, is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical, architectural, archaeological, engineering, or cultural significance. Listing on the National Register recognizes a property's importance to American history but does not place restrictions on private owners; it does, however, make properties eligible for federal historic preservation tax incentives and enables consideration in federal planning decisions. National Historic Landmark designation, the highest level of federal recognition, is reserved for properties that possess exceptional national significance in the history, architecture, archaeology, engineering, or culture of the United States. This property is recorded in the National Register under reference number 70000554. It was listed on August 28, 1970.
