Josselin Castle

Josselin Castle (French: Château de Josselin, Breton: Kastell Josilin, Latin: Castellum Joscelini) is a medieval castle at Josselin, in the Morbihan department of Brittany, France, first built in the 11th century and rebuilt at various times since. It has been designated as a monument historique since 1928.

Guéthénoc, vicomte of Porhoët, Rohan and Guéméné, began to build the first castle on the site around the year 1008, choosing a rocky promontory overlooking the valley of the Oust. The new fortress was named after Guéthénoc's son, Goscelinus. The name is recorded in the Cartulary of Redon Abbey (1080) as castellum et castrum Goscelini, but already by 1108 it was appearing as Castellum Joscelini.

The site chosen for the castle was excellent from both the commercial and the military points of view, and since the 9th century there had also existed an annual pilgrimage in September to the Basilica of Our Lady of the Bramble (Notre-Dame du Roncier), which added greatly to the wealth of the lords and people of Josselin.

In 1154, Odo, Viscount of Porhoet, step-father, guardian and regent of the young Conan IV, Duke of Brittany, collected the Breton lords to deprive Conan of his inheritance, but was defeated by Henry II of England, who was also Duke of Anjou, whose protection Conan had sought. Henry married his fourth son, Geoffrey, to Conan's only child, Constance, Duchess of Brittany, and Henry and his son pulled Josselin Castle down in 1168 and 1175. Henry II himself led the demolition and sowed salt into the ruins.
