Lower Cedar Point Light served navigation on the Potomac River off Lower Cedar Point in Maryland as part of the chain of aids guiding Chesapeake and Potomac waters. The site was first marked by lightships beginning in 1825, and its vulnerability was exposed in 1861 when Confederate forces burned the stationed lightship during the Civil War. In 1867, a screw-pile lighthouse replaced the lightship, but that structure burned on Christmas Day in 1893 and was rebuilt in 1896. The rebuilt lighthouse remained in service until 1951, when it was removed and a skeleton tower was erected on the old foundation, continuing to mark the location.
