Dreamy little river, where you can take a boat trip. In the houses there are small structures where washerwomen used to work. It is recreated with life-size figures.

Path to the weir is a bit hidden. But worth it for a short detour.

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.

Guided electric boat trips on the Trieux past historic washhouses. In French or English. Typical small Breton town. Tour 15 minutes.

The Château de la Roche-Jagu is a beautiful fortress built in the 15th century that proudly overlooks the Trieux estuary, giving it a strategic surveillance asset at the time due to its unobstructed view. Today, its patrol path offers all visitors an exceptional panorama of the entire valley. Nature lovers will stroll in the castle park, labeled "Eco Garden" and "Remarkable Garden", whose exceptional landscaping encourages introspection and contemplation.
