Château de Maillé, Medieval castle in Plounévez-Lochrist, France

Château de Maillé is a stone castle in Brittany featuring a distinctive Renaissance pavilion with three orders of columns and several grand interior staircases. The structure combines medieval foundations with later-added elegant architectural elements.

The site began as a wooden castle on a feudal mound, Coëtseizploë, named for its jurisdiction over seven parishes; Alain de Kermavan was its 13th-century lord. A stone castle was built around the 14th century under Tanguy de Kermavan. In 1577 Claude de Ploësquellec married François de Maillé, and the domain passed to the Maillé family. The north-west wing was roofless and ruined by 1747; it was demolished in 1789 and the rest restored.

The castle takes its name from a family that has shaped it since the 16th century. The stone walls and Renaissance details show how local nobles displayed their power and wealth through architecture.

The château is a private residence owned by the Danguy des Déserts family, so visits must be arranged in advance with the owners; there is no casual drop-in access. It stands in the countryside of Plounévez-Lochrist, in Finistère, and the grounds are not set up as a public visitor site.

The family chose to expand and restyle the castle with Renaissance details in the mid-16th century to align with French fashion trends of the period. This transformation made it a notable example of architectural style shifts in Breton heritage.
