Fort Mifflin

Located on the scenic Delaware River just outside downtown Philadelphia, Fort Mifflin is one of the most unique historic sites in the country. Fort Mifflin has been designated a National Historic Landmark by the United States Congress.

The Fort was originally built by the British in 1771. It is the site of the largest bombardment the North American continent has ever witnessed. In 1777, during the American Revolution, a valiant five-week battle took place when the British Navy attacked Fort Mifflin on Mud Island. It was reconstructed in 1798 as one of the coastal defenses of the era. An active military post until the Korean War, this made the Fort one of the longest continually used military posts in the nation up until that time. The Fort has played many roles in the security of our Nation in its 235 years of existence; garrisoned in the War of 1812, a Confederate prison during the Civil War and a munitions depot in World Wars I & II.

The Fort is home to 14 restored historic structures constructed from 1778 to 1875.
