Château de la Gaubertie, 15th century castle in Saint-Martin-des-Combes, France.

Château de la Gaubertie is a castle built at the end of the 15th century on a hill between Clermont-de-Beauregard and Saint-Martin-des-Combes. Its 16th-century logis runs northeast to southwest, flanked by three towers: a square one at the south corner and two round ones at the west and north corners, with a turret at the east corner. The logis and towers are encircled by machicolations. About 30 metres east stands the chapel, with a square turret and a Gothic dormer window, and large outbuildings adjoin it to the north.

The site started as a fortified house called La Borie before being rebuilt in its current form in the late 15th century. Following the Wars of Religion, the castle underwent restoration work that adapted it to changing times.

The castle's name reflects its connection to the local family who shaped it, and its design shows how nobility balanced everyday living with defensive needs during turbulent times. The defensive features like the machicolations reveal how residents had to protect their homes against threats.

The castle is a private property and cannot be visited; it stands on a hillside between Clermont-de-Beauregard and Saint-Martin-des-Combes, 500 metres west of the D21 road. The chapel lies about 30 metres east of the main building, with the outbuildings attached to its north. Views of the complex are from the surrounding lanes.

The chapel stands about thirty metres east of the main building and has a square turret and a Gothic dormer window. North of it are the estate's large outbuildings. The castle and chapel were listed as monuments historiques on 29 November 1993.
