It is marked by six lighthouses including the Saint-Mathieu Lighthouse and the Kermorvan Lighthouse. The passage maintains a depth of at least 25 feet (7.6 m) at low tide, and is the usual path taken by yachts sailing between the English Channel with the western coast of France.

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 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 naval Battle of Saint-Mathieu took place on 10 August 1512 during the War of the League of Cambrai, near Brest, France, between an English fleet of 25 ships commanded by Sir Edward Howard and a Franco-Breton fleet of 22 ships commanded by René de Clermont. It is possibly the first battle between ships using cannon through ports, although this played a minor role in the fighting. This was one of only two full-fledged naval battles fought by King Henry VIII's Tudor navy, along with the later Battle of the Solent. During the battle, each navy's largest and most powerful ship — the Regent and the Marie-la-Cordelière (or simply Cordelière) – were destroyed in a large explosion aboard the latter.

Porspoder (French pronunciation: [pɔʁspɔdɛʁ]; Breton: Porspoder) is a commune in the Finistère department of Brittany in north-western France.
