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.

High viewpoint over the Briére marsh

many intersections, heavy traffic in summer

Very beautiful circuit through the countryside between Morbihan and Loire-Atlantique, passing through Briandais and the Château de la Roche Hervé.

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.

Built in the 14th century and rebuilt in the 19th century, the Château de la Bretesche stands out for its privileged location on the water's edge. Seeing it suddenly appear as you cycle along the D2 is a splendid sight.

To do in different seasons to see the evolution of the marsh.

Free observation tower at Port Rozé.
