Mary Island Light

Mary Island Light is a lighthouse on a strategic point along the Alaskan coast that guides maritime vessels through complex waterways. The structure sits on a remote island without road access and features traditional construction with light and signaling equipment.

The lighthouse was built in 1903 and has served as an important navigation aid for ships in the region since then. Its historical importance was recognized through listing on the National Register of Historic Places.

The lighthouse is a reference point for fishing communities in the region and shows early maritime architecture of the 20th century. Local people and visitors recognize its importance as a historic landmark along the southeastern Alaskan coast.

Access is only by boat or seaplane since the island has no road connections. Visitors should prepare for rough sea conditions and changeable weather, especially during months outside of summer.

The lighthouse sits in an area with particularly difficult navigation conditions and irregular coastlines. The precise positioning of the light enables ships to find safe routes through the branched island groups.
