The Semáfor building is a surveillance building erected in 1887 to regulate coastal maritime traffic. It is currently a lookout over the protected beach and is accessed by walking along a wooden footbridge that crosses the wetland area.  Access to the beach from the Semàfor is not allowed. Very close, we find the Carabinieri barracks.
