Architecture

The Sand Island Lighthouse is built from local limestone and features a distinctive square tower. The structure's design was influenced by the prominent lighthouses of the time, with a characteristic rounded lantern room at the top.

The light source used during its operational period was a Fresnel lens, which provided an effective beam for navigation.

Light Characteristics

The Sand Island Lighthouse emitted a fixed white light from its lantern room, visible to mariners up to 20 nautical miles (37 kilometers) away.

Its primary function was to guide vessels into Mobile Bay and the Gulf of Mexico.

Current Status

The tower serves as a reminder of the region's rich maritime history.

Heritage Status

The Sand Island Lighthouse was listed on the National Register of Historic Places (NRHP) in 1975, with reference number 75000305.

It is also recognized under the State of Alabama's historic preservation program.
