My favorite route around Pornic starting from Tharon Plage along paths in the middle of nature, secure cycle paths, the pleasant side of the very rolling Vélocéan, to recommend.

Former residence of the Barons of La Roche Bernard and center of Protestantism. The castle impresses with its romantic and fairytale side. Only the courtyard is open to the public (the interior of the castle is not accessible).

In the middle of this tangle of branches, brambles, appear mounds of earth, scattered stones, sections of walls, the only witnesses of the distant presence in this place of a fortress. The castle of Lorieux ("loc-rieux", the place of the Rieux, noble family), was built at the same time as the large surrounding fortresses, on the orders of Alain the Great, king of Brittany, in order to protect his kingdom from the Norman invasions. Around 1130, the castle became the residence of the Viscounts of Donges, but during the Wars of Religion, the troops of the Duke of Mercoeur attacked the castle. Later, in 1614, Richelieu decreed the disappearance of this fortress, considered a Huguenot lair. In 1618, the leveling order was carried out. Legends abound on these mysterious ruins. It is said that underground passages start from this fortress.
