The castle was built in the Gothic style starting in 1306, on the site of an earlier castle. It is surrounded by water-filled moats and an English garden, in the centre of a Bordelais vineyard. Despite modifications over the centuries, it has kept its character as a fortress. At her death in 2004, the Countess of Chabannes, a descendant of Montesquieu and last owner of the château, bequeathed her belongings, including the castle, to the Foundation named after her. The castle is open to visitors from Easter to 11 November. It is classed by the French Ministry of Culture as a monument historique.
