Sémaphore de la Pointe Saint-Mathieu

The Sémaphore de la Pointe Saint-Mathieu is a signal station that monitors vessel traffic in Plougonvelin on the Brittany coast. The structure rises about 39 meters above sea level and observes ship movements at the entrance to Brest harbor and along the Chenal du Four waterway.

The first station of this kind was established in 1806 and the current structure dates from 1906 to improve visibility over the waterways. The construction was a response to growing maritime safety demands in one of France's busiest shipping areas.

The location stands alongside a national memorial for sailors lost at sea, featuring a notable sculpture by artist René Quillivic. Visitors can experience this tribute and sense the connection between the signal station and the region's seafaring past.

The location functions as a watch point for vessels and boats traveling in the area. Visitors should be aware that this is an active operating facility and access or tours may be restricted.

The station grounds occupy one of France's busiest shipping routes, where the Atlantic Ocean meets the English Channel. This strategic position makes it a watch point for hundreds of ships that cross these waters daily.
