Dreamy little river where you can take a boat trip. The houses have small structures where washerwomen used to work. This is recreated with life-size figures.

Château de la Roche-Jagu was built at the beginning of the 15th century in the Trieux valley in Brittany. Construction presumably took place between approximately 1405 and 1418. It was created for Catherine de Troguindy, a member of the Breton nobility. The location was chosen for its strategic position on a rocky outcrop. From there, the Trieux river and the traffic routes in the valley could be controlled. The complex served both as a residence and as a fortified manor house. During the Breton War of Succession, the region was repeatedly contested. The complex also suffered damage. After the conflicts, the building was repaired and partially rebuilt. The architecture remained strongly influenced by military functions. In the late Middle Ages, the castle developed into a representative noble residence. It thus reflects the transition from pure defensive architecture to the residential and power display of the nobility.

A path rather than a road that comes across a somewhat unexpected passage with a beautiful view from above.
