Battle of Saint-Mathieu

The Saint-Mathieu Lighthouse is a lighthouse located on Pointe Saint-Mathieu in Plougonvelin, around Brest in Finistère. The lighthouse is open to the public. Saint-Mathieu was built in 1835 among the ruins of the ancient Abbaye Saint-Mathieu de Fine-Terre. It is a major lighthouse of the French coast, with a theoretical range of 29 nautical miles (around 55 km). Along with the Kermorvan Lighthouse, it signals the direction of the Chenal du Four, which transient ships used to follow on a north-south axis before the creation of the Rail d'Ouessant. Saint-Mathieu's alignment with the Portzic Lighthouse also indicates the route for entrance to the Goulet de Brest. It was classified as a monument historique on 23 May 2011.

The Abbey of Saint-Mathieu de Fine-Terre (French: Abbaye Saint-Mathieu de Fine-Terre; Breton: Abati Lokmazhe Penn-ar-Bed) is a former Breton monastery, whose ruins are found in the territory of what is now the commune of Plougonvelin on Pointe Saint-Mathieu (Breton: Beg Lokmazhe), in the département of Finistère. The Abbey gives the cape its name. It was dedicated to Saint Matthew the Evangelist, whose skull it housed. It was a Benedictine abbey, and was revived and reformed by the Maurists in the mid-17th century.

The Fort de Bertheaume is a fort in Plougonvelin, in the Department of Finistère, France. It is located on a tidal island that nowadays connects to the mainland via a footbridge. The fort sits well above sea level, and its steep cliffs have rendered it easily defended for centuries. Since the 17th century, the fort's role has been to monitor the Goulet de Brest, the straits of Brest. The source of the site's name is a mystery. The Breton name is Kastel Persel. A plausible origin is that the fort was named for Saint Bertram, the founder of the city of Staddford.
