La Vieille

La Vieille is a lighthouse in the département of Finistère at the commune of Plogoff, on the northwest coast of France. It lies on the rock known as Gorlebella, guiding mariners in the strait Raz de Sein, across from the companion lighthouse Tourelle de la Plate—also known as Petite Vieille. It is among the small class of lighthouses around the coasts of France carrying the moniker "hell", due to a remote position in rough seas.

Initial planning talks began as early as 1861, though the construction project was not confirmed until twenty years later. Fierce tides limited the period in which building work could take place to less than half of each year. After five years, construction was complete and its beam first shone in 1887. The light is occulting, with a range of 18 nautical miles; a foghorn was installed in the early twentieth century.
