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.

Unfortunately we didn't see it when we arrived (30.8.24) in the rain. The next day, when it was humid and dry, we were able to marvel at this enormous animal.

One of the 5 semaphores on the estuary created by the artist Vincent Mauger. Beautiful view of the meadow and the Taillée canal. Unfortunately positioned too far from the river. Undoubtedly more spectacular during periods of flooding and at high tide.

The little bridge no longer exists, you can walk there but you have to get wet and do a little climbing :)
