A medieval fortress originally built in the 12th century and reconstructed multiple times throughout its turbulent history. The castle was demolished in 1395 by the Duke of Brittany due to its owner's rebellion, then rebuilt in 1406, and partially dismantled again in 1626 on Richelieu's orders after another conspiracy. The fortress features impressive defensive architecture including a barbican, gatehouse with 6-8 meter thick walls, and two major towers - the Tour de Rougé and Tour d'Acigné - both over 20 meters high.

This defensive medieval castle, perched on a rocky spur overlooking the Léguer valley, has no less than 11 towers and two dungeons! Built by the lords of Coëtmen Penthièvre and today owned by their descendants, it lived through the most glorious but also the most difficult hours of Breton history. Open from April 1 to November 1, days and times vary depending on the period.

Loc-Envel is one of the smallest communes (settlements) in Brittany and you ride into it and out of it in almost the same moment. Still, nestled into the hilly landscape south of Belle-Isle-en-Terre, it's particularly charming with pretty houses and an old church.

Today's castle complex was built in the 15th century in place of a previous fortification from the 12th century. This was built on behalf of the Coëtmen-Penthièvre family. The lords of the castle Rolland II. and Rolland III. de Coëtmen were allied with Olivier V de Clisson, who was on the side of Charles V and therefore at odds with John IV, Duke of Brittany. In 1395, the old castle was partially demolished on Johann's orders.

The castle of Tronquedec dominates the Léguer river by its stature and its strategic position on its rocky outcrop. It is a marvelous witness to the local history of the region, to the Dukes of Brittany and to medieval times.
