Pointe de Corsen Lighthouse

The Pointe de Corsen Lighthouse marks the westernmost tip of mainland France, in the commune of Plouarzel (Trézien), at the far edge of Finistère in Brittany. This is where the land runs out and the open Iroise Sea begins — the point conventionally taken as the dividing line between the English Channel and the Atlantic.

Where exactly is the lighthouse?

The lighthouse stands on the rocky headland of Pointe de Corsen, a few hundred meters from the CROSS Corsen station, the regional maritime surveillance and rescue centre that monitors one of the busiest shipping lanes in the world, running past the island of Ouessant. The light was first put into service in 1894. It was originally a tower attached to a keeper's house — that house now stands in ruins — while the light itself continues to operate as a directional beacon, guiding ships safely through the Chenal du Four.

How do you get there?

The easiest route is by car from Brest (about 25 km) toward Plouarzel, then a short local road straight to the headland, where parking is available on site. The area around the lighthouse has been developed with accessibility in mind: an interpretive trail leads to a viewing table and has been made fully accessible for visitors with reduced mobility — a rare feature among Brittany's rugged headlands, which usually demand scrambling over rocks.

What will you see on site?

The viewing table helps you pick out the other lighthouses scattered along the horizon — this is one of the few spots where several lights guarding the Chenal du Four and the Iroise Sea are visible at once. On a clear day you can make out the silhouette of the Molène archipelago and the island of Ouessant. The lighthouse itself is unmanned today and not staffed on-site, so visitors admire it from the outside while walking along the cliffs. A detail film buffs will appreciate: the lantern room of the Phare de la Jument, off Ouessant, was recreated here for the 2004 film "L'Équipier" by director Philippe Lioret, to shoot its lighthouse interior scenes.

When should you visit?

The headland is open year-round, but this is a place that shows its true character in strong wind — autumn and winter bring waves crashing dramatically against the rocks, so dress warmly. Summer generally offers better visibility and a more comfortable walk along the coast, though there's little shade. Sunsets over the Iroise Sea, with the lighthouse silhouetted in the foreground, are among the most photographed views in this part of Brittany.

What else is worth combining with a visit?

A dense network of coastal footpaths (the GR34) runs through the area, along with several other lighthouses of the Iroise region, together making up a full day's worth of walking. It's a natural starting point for a longer stroll along the cliffs toward neighboring beaches and headlands.

Frequently asked questions

Can you go inside the lighthouse? No — it's an active, remotely operated directional light with no permanent keeper, and it isn't open to visitors inside. You view it from the outside.

Is this the same building as the Trézien Lighthouse? No. These are two separate lighthouses in the same area, about two kilometers apart — the Trézien Lighthouse stands further inland and serves a different navigational role, working together with the light at Pointe de Corsen.

Is the site wheelchair-accessible? Yes, the path leading to the viewing table on the headland was designed for full accessibility for visitors with reduced mobility.

Why is this spot called "the edge of the world"? Because geographically it's the westernmost point of mainland France — beyond it lies only the open Atlantic and the island of Ouessant.
