Mathias Point Light, Navigational lighthouse at Potomac River, Maryland
The hexagonal lighthouse stands on screw-pile foundations in the Potomac River, featuring a fifth-order Fresnel lens that emits green flashing signals.
Constructed in 1876 after engineering studies recommended shifting the location from Quantico to Mathias Point, the lighthouse guided vessels through Port Tobacco Flats.
The lighthouse design incorporated three tiers of ornamental woodwork, representing the craftsmanship and architectural styles of late 19th century maritime structures.
The automated beacon now occupies the original foundation at coordinates 38°24′18″N 77°02′34″W, maintaining its role for maritime navigation through the Potomac River.
The structure underwent a transformation from a manned lighthouse to an automated signal station in 1951, before its complete replacement with a metal tower.
