Trezien lighthouse

From its height of 37 metres, the Trezien lighthouse illuminates the open sea for up to 32 km. Up there, you'll be between heaven and earth, contemplating the coast and sea as you've never seen them before!

Erected in 1894 and automated a century later, the Trezien lighthouse stands 500 m from the shore in the commune of Plouarzel at the tip of North Finistère.
Standing 37.20 m high, it stoically watches over the southern entrance to the Chenal du Four. This channel is the main navigation route for heavy-duty boats daring to sail between the islands and the mainland.

The Trezien lighthouse allows visitors access to its lantern, whose directional light illuminates the open sea up to 32 km off the coast. Take your time to climb the 182 steps that wind their way up the granite ashlar masonry tower from Aber Ildut. You'll have access to a stunning panorama from the Saint-Mathieu lighthouse to the Four lighthouse, from the islands of the Mer d'Iroise to the tip of Corsen, home to the Cross Corsen regional maritime rescue center.
