Château de Costaérès
Château de Costaérès, Gothic Revival château on île de Costaérès, France
The granite château stands on an islet in Trégastel, featuring a circular turret, multiple roof styles, and regular stone courses with polygonal masonry.
Polish engineer Bruno Abakanowicz purchased the islet in 1892 and constructed the château by 1896, employing engineer Lanmoniez and entrepreneur Pierre Le Tensorer.
The interior construction incorporated wood salvaged from the Maurice sailing ship, which ran aground during winter 1896, adding maritime heritage to the structure.
The château remains in private ownership, situated within the protected Natura 2000 zone of Côte de granit rose-Sept-Îles in Brittany's Côtes-d'Armor department.
The name Costaérès derives from Breton language meaning 'old drier', referring to the islet's past function as a fish drying location.
