La Croix Lighthouse, Stone lighthouse in Côtes-d'Armor, France

La Croix Lighthouse is a stone structure standing 13 meters tall on the left side of the channel approach to Lézardrieux port, positioned between Bréhat Island and Ploubazlanec. White paint on its eastern face combined with red crenellations makes the tower visible to approaching vessels from multiple directions.

A first lighthouse was built here between 1865 and 1867: a 13-metre cylindrical tower with a small attached stair turret. In 1944 the German army destroyed its upper section. It was restored to the same design in 1949 and given a white occulting light with a four-second cycle. A wind turbine once stood on top, replaced by a photovoltaic solar module in the early 2000s.

The lighthouse appears in Joris Fleurot's horror short film "La croix", which was nominated at the 31st Gérardmer Fantasy Film Festival in 2024 and at Filmoramax in Lyon the same year. The film shows the tower at several points and gives it esoteric properties.

The lighthouse sits at the mouth of the Trieux River and is accessible only by water, whether by boat or kayak. Visitors should check local sea and tidal conditions beforehand, as weather in this coastal area can change quickly.

The tower's top once carried a wind turbine that powered its light; a photovoltaic solar module replaced it in the early 2000s. The lighthouse also appears in Joris Fleurot's horror short film "La croix", nominated at the 31st Gérardmer fantasy film festival in 2024, where the monument is given esoteric properties.
