Château de Montcony, Medieval castle in Montcony, France.

Château de Montcony stands on a quadrangular terrace bordered by four round brick towers with conical ochre-tiled roofs and covered machicolations. The two northern towers, five storeys high, flank a rectangular main building with one full storey and an attic, extended south by two short right-angled wings. A hexagonal tower in the north-east corner of the courtyard holds a stone spiral staircase.

Construction of the castle began in the 13th century as a feudal stronghold. In the 15th century, when Guillaume de Montcony held the title of lord, Duchess Isabella of Portugal was received here.

The La Rodde family held Montcony from 1712 into the 20th century, and several of its members served as mayor, including Charles-Louis, first mayor of the commune, who died in 1792. The family motto was Audaces fortuna juvat. The castle is private and cannot be visited.

The castle is private property and cannot be visited; there is no public access to the interior or the courtyard. It stands in the centre of Montcony beside the D23 road, on a motte on flat ground at the top of a small hill, so it can only be seen from the public road outside.

The north-east tower, at 41 metres the taller of the two northern towers, was re-roofed between 2002 and 2005 under Frédéric Didier, chief architect of historic monuments, together with the east wing of the main block. The owners received the regional heritage first prize in 2006 for the work.
