Old mill dating from the 16th century. Located on private property, but relatively visible from the road. Whether you climb up from Angellerais by road or via the GR3 trail, it will require a good effort.

Built in 1854 at a time when Paimboeuf was the advanced port of Nantes, before being replaced by Saint-Nazaire. It is the only lighthouse on the Loire and the most "land-based" in France because it is 10 km from the ocean.

This former, very active fishing and barge unloading port probably takes its name from the colour of the shutters of the house right next door. Departure of the coastal path towards Saint-Brévin. Toilets.
