Sémaphore de l'île de Batz

The Semaphore of Batz Island is a maritime signal station that monitors vessel movements and communicates with maritime authorities. It operates continuously and works to coordinate shipping traffic in this area of the English Channel.

The original station was built in 1866 near the lighthouse and later moved to a different location in 1905. It was heavily damaged during World War II and was rebuilt in 1952.

The station reflects Brittany's maritime traditions and how people on the island stay connected to the sea's safety and movement. You can observe how local practices blend with modern coastal surveillance in everyday work.

Visiting is best in good weather since the island is reached on foot and the path can be difficult depending on tidal conditions. Check local conditions before your visit to find the best times to reach the site.

The station uses the Spationav system, which combines many data sources to track all vessels in the region and coordinate rescue operations. This makes it one of the most important monitoring stations on this coast.
