The Château de Tonquédec is one of the most visited monuments in the département of the Côtes d'Armor. The castle ruins with its several towers and a closed curtain wall is one of the most impressive French medieval sites. From the height of a rocky cliff it dominates the valley of the Léguer. It is a genuine vestige of feudal Brittany. The present castle was built in the 15th century, on the site of an earlier 12th-century castle (built by the Coëtmen-Penthièvre family). It was partially dismantled by order of Jean IV, Duke of Brittany, in 1395 because of a conflict between him and the Penthièvres. Indeed, Rolland II and Rolland III of Coëtmen, Viscounts of Tonquédec, had allied themselves to the rebellion of Olivier de Clisson.
Reconstruction began in 1406 by Rolland IV of Coëtmen. The castle subsequently changed owners several times, before becoming an artillery base in 1577. At this time, the owning family (Goyon de La Moussaye), being Protestant, was therefore in disagreement with the king, Henri IV. During the War of the League, the castle was a hiding place for Huguenots. It was finally dismantled around 1622 on the orders of the powerful Cardinal Richelieu.
The castle currently belongs to descendants of the original builders, House of Coëtmen-Penthièvre. The entrance gate leads to an outer fortified courtyard or basse-cour. Two towers, joined by a curtain wall, frame the entrance to the inner courtyard which is reached by a postern, once protected by a moat and drawbridge. The keep with walls 4m thick, stands detached from the curtain walls, at the rear of the ensemble. The ruins may be visited from April to October.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
