At the beginning of the 20th century, Georges Turpault, a spinner from Cholet, bought an old house and the adjoining land on the tip of Beg-er-Lann, located to the south-west of the Côte Sauvage of the peninsula of Quiberon. He entrusts the entrepreneur Hippolyte Jamet with the construction of an Anglo-medieval style castle which he calls “the castle of the sea”. Its construction took place from 1904 to 1910. During the Second World War, the castle was occupied by the German army, which built two blockhouses there, severely degrading it. In 1946, at the end of the war, Mrs. Turpault sold the castle to the mayor of Quiberon, Marcel Robert. The latter will partially restore it before reselling it to Ferdinand Richard in 1967.
Significant restoration work is carried out by the Richard family. Put up for sale in 2010, the château found a buyer in 2014.
