of the Rocheforts
The first known lord is Abbon de Rochefort, in 1118.
This name already evokes the existence of a fortress.
The lords of Rochefort-en-Terre enriched and expanded their domain considerably by various alliances. In 1374,Jeanne de Rochefort and Jean de Rieux II married, and then became one of the most powerful families in the duchy of Brittany.
In1488,Jean VI de Rieux-Rochefort, who was leader of the Breton army, lost the battle of St-Aubin-du-Cormier against France Charles VIII, it was then that his fortresses were dismantled.
ThenAnne de Bretagne, having become queen, granted a compensation of 100,000 gold ecus, to her former guardian, which would allow her to renovate her castle of Rochefort.
