Lochrist Light

Lochrist Light stands in the hamlet of Lochrist, part of the commune of Le Conquet, on the western tip of the Finistère peninsula in Brittany. The tower sits roughly 600 metres inland from the coast, near Porsliogan beach, and while it looks every bit like a classic lighthouse, it's technically classified as a "feu" — a navigational light rather than a full lighthouse.

How do you get there?

The easiest approach is the D789, the road linking Brest and Le Conquet — signs pointing to the village of Lochrist appear along the way. An alternative is the coastal path running between Pointe Saint-Mathieu and Le Conquet, from which a marked turn-off leads to the village, directly opposite Porsliogan beach. If you're already walking the Iroise coastline, Lochrist makes a natural stopping point between Pointe Saint-Mathieu and Le Conquet, so it's worth combining the visit with a short stretch of coastal trekking.

What will you see there?

The tower is octagonal and rises 18 metres. Its most distinctive feature is the two-tone paint job: the landward side is white, the seaward side red — a scheme that helps sailors judge their bearing at a glance from far offshore. An observation platform at the top offers a full 360-degree panorama, taking in both the Iroise Sea coastline and the farmland of inland Finistère.

Lochrist Light doesn't work in isolation — its whole navigational purpose depends on lining up with the Kermorvan lighthouse in Le Conquet. When a sailor sees the two lights stacked exactly one above the other, they know they're holding a precise bearing of 137.9 degrees toward the Stiff lighthouse on Ouessant — the safe route through the Helle channel, which links the Four channel to the Fromveur channel. That channel itself is a remnant of a river mouth that extended further out to sea tens of thousands of years ago, now submerged — one reason the seabed here is complex enough to need such precise alignment markers.

Inside the tower sits a Fresnel lens that concentrates the beam so tightly its theoretical reach exceeds 42 kilometres, though the official navigational range is listed at 23 nautical miles. The light's signature is a white flash occulted in a "2+1" pattern every 15 seconds — a rhythm sailors use to distinguish it from every other light along this stretch of coast.

When should you visit?

The tower's interior can only be visited at specific times of year, arranged through the Le Conquet tourist office — it's worth calling or emailing ahead to confirm the current schedule. From the outside, the light can be admired year-round, though clear spring and summer days offer the best visibility, both of the tower itself and of the surrounding Iroise coast.

Frequently asked questions

Is Lochrist Light an actual lighthouse? Not formally — it's classified as a navigational light (feu), meeting only one of the four criteria required for full lighthouse status. Functionally, though, it does the same job: guiding ships along a safe course.

What's the point of aligning it with Kermorvan lighthouse? When the two lights appear stacked in a single line, sailors know they're holding an exact bearing of 137.9 degrees through the Helle channel toward Ouessant and the Stiff lighthouse — a key navigational cue in this part of the Iroise Sea.

Can you climb to the top of the tower? Yes, but only during specific periods of the year set by the Le Conquet tourist office. It's best to confirm availability before visiting.

Where exactly is the light located? In the village of Lochrist, about 600 metres from the shore, directly opposite Porsliogan beach, along the D789 road between Brest and Le Conquet.
