The Jones Point Light is a small river lighthouse located on the Potomac River in Alexandria, Virginia. It was built in 1855. It is a small, one-story house with a lantern on top and served primarily as a warning light for naval ships approaching the Washington Navy Yard. The lighthouse is located on Jones Point in Alexandria and is part of Jones Point Park. Visitors can approach the lighthouse, but it is currently impossible to enter the building. A gravel interpretive trail explains the human and natural history behind Jones Point Park. Exhibits highlight the area's freshwater marsh habitat, its use by American Indians, and its role in shipbuilding and navigation. Two fishing piers are an excellent spot to cast for American catfish, rock bass, and American eels.
