Very pretty pond with a very special atmosphere. It was the pond of the Lestrenig manor.

It’s a beautiful little roadside sanctuary. The name of this place comes from the Breton word Roz which means height. Historians confirm that at this location, even if it is very degraded and there are very few traces left, a feudal mound overlooked the passage.

Will you find it? This fountain is a rather curious construction, here no pool in the open air as one would expect, it is even closer to the well.

Easily accessible from a path on the edge of Liziec, an ideal space to cool off on hot days, the cave of John II is in fact a heap of rock. She said her name to the Duke of Brittany Jean II, the latter according to legend liked to walk there, along the Lizier as we do now (even if the place has changed a lot since).
