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.

This small church is actually an extension of a 14th-century chapel, which is believed to be the current sacristy. The church in its present form was reportedly completed in 1606 or 1628, depending on the source. In any case, it's a fairly old church for the region.

The Saint-Nazaire U-boat bunker is one of five German U-boat bases built on the French Atlantic coast during World War II. The 301-meter-long bunker was built in just 16 months in 1941/42 using almost half a million cubic meters of concrete. Several hundred men were stationed here until May 1945; offices, workshops, and a medical center were housed under the roof, which was up to 9.60 meters thick. It was built on the site of the former overseas port from which steamers departed for Central America.

It's probably an oil refinery, but it reminded me of Mordor! It's eerily beautiful how the fire shoots noisily out of the chimneys.

Small river port, fishing and marina, where you can visit the "Terre d'Estuaire" museum on the theme of the Loire estuary. Picnic tables, restaurant, restrooms, and drinking water are available. The footbridge, like the bridge, provides access to Villa Cheminée on the western tip of the island.

Escal' Atlantic is a fascinating museum that will take you aboard a liner 100 years ago. The interactive exhibition informs you about the liners of the time and many contemporary objects are exhibited.
