Château de Bonnemie, Historical monument in Saint-Pierre-d'Oléron, France

The château de Bonnemie stands in Saint-Pierre-d'Oléron on the island of Oléron. The square main building has one storey under a roof of hollow tiles, flanked by four slate-covered towers: two square and two round. A lower lodging wing is attached to it. The pale stone walls show patches of exposed stone and fallen plaster, and green shutters frame the windows.

The château de Bonnemie is first mentioned in the 11th century under Ebles de Châtelaillon, first lord of the Bonnemie fief. Its towers appear to date from the 15th or 16th century, while the other buildings are from the 18th century. It belonged notably to the Le Berthon family, barons of Bonnemie, and work carried out in the 19th century left its mark on the buildings.

The château stands in Saint-Pierre-d'Oléron, in the south of the island of Oléron. The building is private and its interiors are not open to visitors; the façades and roofs, listed since 1981, are seen from the surrounding streets. The two square and two circular towers, roofed in slate, are the elements to look for from outside.

The château's square plan is flanked by four slate-roofed towers, two square and two round, while the attached lodging rises one storey above the ground floor. The 19th-century works left visible marks on the buildings, and the facades and roofs were listed as monuments historiques in 1981, with the interiors following in 1994.
