Created by monks in the 12th century, Lac au Duc is the largest of Brittany's inland lakes. Its 250 hectares extend between Ploërmel, Taupont and Loyat.
The dolmens of the Loge Morinais are typical of Breton dolmens. The alley is more than thirteen meters long and almost two meters wide. Few roofing slabs are present, however orthostats are still in place and some are strongly leaning.
It is in the magnificent forest of Brocéliande that the legend of King Arthur takes its source, between moors and ponds. Here is the wonderful world of the fairy Viviane, Merlin the enchanter and the knight Lancelot.
