Union held Civil War Fort.

Built by Confederate POW labor when Washington was threatened by Confederate General Early's raid, and a prison break was feared. It is the only surviving fortification of three that guarded Camp Hoffman, the huge stockaded POW camp established in 1863. It is a small four-sided earthen fort with four reconstructed buildings, and the remains of a powder magazine. It is located on the Potomac River side of the peninsula. The war ended before construction was complete.

The site of the other two works, Redoubts #2 and #3 were located on the Chesapeake Bay side above the prison camp stockade. They were smaller circular earthen works with a moat, armed with four guns each, and a wooden observation tower in the center. Both have eroded away.
