Phare de Chausey, Maritime lighthouse in Granville, France.

Phare de Chausey is a stone lighthouse in Granville, with a square tower that rises prominently from the flat island landscape. The structure was designed to guide vessels through the complex waters of the Chausey archipelago.

Construction of the lighthouse began in the 1840s with support from leading engineers of that era. The project used stone from local quarries, connecting the building method to the island's landscape.

The name refers to the Chausey archipelago that dominates the seascape of this coastal region. It represents the deep connection between local communities and the sea that has defined life here for centuries.

The lighthouse sits on an island within the Chausey archipelago, accessible from Granville. Visitors should know that reaching the site depends heavily on tidal conditions.

The lighthouse's square tower rises 19 metres, placing its light 37 metres above the sea. Its granite came from quarries on the island itself, and the foghorn originally stood 80 metres from the keeper's house, facing the water, before being moved beneath the lantern. The optic was replaced on 15 September 1903.
