Château d'Andert, Historic castle in Andert-et-Condon, France.

Château d'Andert is a former fortified house on a grassy rise in Andert-et-Condon, 1.5 km south-southeast of Rossillon. Its central round tower carries a steep dark conical roof with a small finial; a lower wing with a dark pitched roof, small rectangular windows and a reddish chimney runs to its left, and a taller block with a broad dark roof and a small turret stands to the right. A low stone wall draped with vegetation sits at the base.

The Andert knights are documented from 1180, and the seigneurie passed through the Grammont, Migieu and Paraz families. On 3 August 1532 a division of property between the Grammont brothers Charles and Humbert assigned the fortified house to Charles. In the 17th century it became a pleasure house, as a carved date of 1655 attests, and it was partly remodelled in the 19th century in Neo-Gothic style.

The Andert family gave its name to the seigneurie, whose knights are documented from 1180; the estate later passed to the Grammont, Migieu and Paraz families. On 3 August 1532 the brothers Charles and Humbert de Grammont divided their joint property, and the fortified house and seigneurie went to Charles. A date carved in 1655 records the house's conversion into a pleasure residence.

The castle is privately owned and visits require advance arrangement with the owners. Historical information and documentation about the building can be found at the Heritage and Photography Media Library.

The 1655 date carved on the building marks its conversion from a fortified house into a pleasure residence, a change tied to Guy de Migieu, king's councillor and former president of the requests of the palace in Dijon, who bought the estate after it fell into dispute among the creditors of the La Balme heirs.
