Mathias Point Light

Mathias Point Light is a hexagonal lighthouse standing on screw-pile foundations in the Potomac River in Maryland. The structure features a Fresnel lens that projects green flashing signals to guide boats through the waterway.

Built in 1876 following engineering studies that recommended moving the location from nearby Quantico to Mathias Point, this lighthouse helped ships navigate the shallow waters around Port Tobacco. The beacon served river traffic for decades before technological changes transformed its purpose.

The lighthouse design incorporated three tiers of ornamental woodwork, representing the craftsmanship and architectural styles of late 19th century maritime structures.

The lighthouse stands on its original foundation and now operates as an automated beacon for river traffic on the Potomac. The structure is located on the water and is only accessible by boat, which is important to keep in mind when planning a visit.

In 1951 the original lighthouse became automated and operated without crew members stationed there. Later a complete replacement with a metal tower occurred, yet the current structure still functions from the same historic location.
