A fit cyclist, but not recommended in December. Beautiful route, but it's hard-earned.

The castle once dominated the Vilaine River from a rocky spur, controlling a strategic river and land route. It was fortified with moats, gates and towers, and its county belonged to the powerful Rieux family.

I really didn't understand how to get to the dolmen. The path that was supposed to go there was blocked off. I was able to take a photo over the hedge of the field next door, but it was still very disappointing.

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.
