Tourelle de la Plate

The Tourelle de la Plate, also known as Petite Vieille (Little Old Woman) is a lighthouse in the dangerous strait Raz de Sein, off the northwest coast of France, belonging to the departement of Finistère in the region of Brittany.

The octagonal turret is supported on a cylindrical base, these two parts being mounted on reinforced concrete.

On December 4, 1896, a violent storm broke over the tower which was "beheaded".

On August 31, 1911, a permanent green fixed light, burning oil, was installed.

Currently, the tower has the role of warning ships to keep to the west of the light.
