La Balue lighthouse, Maritime beacon in Saint-Malo, France.

La Balue is a land lighthouse near the Saint-Servan district of Saint-Malo, built as a square tower of rough-cut tan and gray stone blocks set against a dwelling that once held the keeper's room and stores. Five white-framed windows, each split by a vertical mullion, run in a single column up the facade. Aligned with the Bas-Sablons lighthouse, it marks the Petite Porte inner channel into the port.

The original structure was built in 1868, but German forces destroyed it during World War II in 1944. An identical replacement was rebuilt and completed in 1948, becoming part of the postwar reconstruction effort.

The lighthouse serves as a navigation aid that sailors recognize and rely on when approaching the Breton coast. Its green light is part of the maritime communication system that connects seafarers to this historic port city.

Visitors can view the lighthouse from the surrounding coastal areas and accessible paths around Saint-Malo. Early morning or late afternoon offers the best lighting conditions for observing the structure and taking photographs.

The tower stands in line with the Bas-Sablons lighthouse: seen from the open sea, the two mark the entrance to Saint-Malo harbour through the Petite Porte inner channel. The upper part was painted black in 1896, and the light was electrified in 1926.
