Saint-Mathieu lighthouse

Saint-Mathieu Lighthouse stands on Pointe Saint-Mathieu in Plougonvelin, right by Brest, at the far western tip of Brittany where the coast meets the Iroise Sea. It is one of the most recognisable landmarks in Finistère, its tower rising among the ruins of a medieval abbey and beside a monument to sailors lost at sea.

How tall is the lighthouse and how many steps does it have?

The tower is 37 metres high, with its light positioned 58 metres above sea level. A climb of 163 steps leads to the gallery at the top, and the view opens up gradually with every turn of the stairs. The light itself carries a range of around 29 nautical miles, making it one of the more powerful beacons on the Breton coast.

When was the lighthouse built?

The current tower was first lit on 15 June 1835. It was raised on the grounds of a former Benedictine abbey, on a site that had already guided sailors for centuries. It initially burned rapeseed oil, later switched to petroleum, and was electrified in the 1930s. The lighthouse was automated in 1996 and has been remotely monitored since 2006. In 2010 it was listed as a French historic monument.

Why does the lighthouse stand among abbey ruins?

The site's history goes back far beyond the lighthouse itself. In the 6th century, Saint Tanguy founded the first monastery here to house the relics of Saint Matthew. The Benedictine abbey proper was built in the 11th century, and monks maintained it until the French Revolution. From around 1250, they kept a fire burning atop a square, 40-metre monastery tower to warn ships away from the rocky coastline — a direct forerunner of today's lighthouse. After the Revolution, the abbey fell into ruin, though its Romanesque facade, the stone vaulting of the choir, and the arcades of the nave still survive. These ruins sit right next to the modern lighthouse tower, creating an unusual pairing of medieval religious architecture and 19th-century maritime engineering.

What else is there to see on the headland?

Alongside the lighthouse and the abbey ruins, Pointe Saint-Mathieu holds a cenotaph, a national monument dedicated to French sailors who died at sea, erected in 1927. From the viewing platform by the lighthouse, the panorama stretches across the Iroise Sea, and on a clear day the islands of Ouessant and Molène are visible to the west. The port of Le Conquet lies nearby, with ferries departing for both islands.

Can visitors climb the lighthouse?

Yes, Saint-Mathieu Lighthouse is open to the public, and visitors can climb the stairs to the viewing gallery. It is a rare chance to see a working lighthouse up close while also taking in the abbey ruins and the scenery at the very edge of Brittany.
