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.

Not so easy circuit between Beganne and Pellele with beautiful hills including one at 11.4% no need to go to the Col de la Madeleine 😂

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.

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.
