Château de Lacoste, in Salviac, Lot, France

Château de Lacoste is a castle in Salviac with walls dating back to the 11th and 12th centuries, though major rebuilding happened in the 15th and 16th centuries. The structure features thick stone walls, towers, spacious rooms with archways, and vaulted ceilings that show centuries of craftsmanship and modifications.

The barons of Gourdon founded Salviac in the 10th or 11th century, and the castle stands on the site of the Cazelles tower, a noble house probably built in the 13th century. Remodelled around 1500 around a circular stair tower, it took the name Lacoste when it passed to the Gransault-Lacoste family. Pierre Gransault de Lacoste bought it in 1780 from the heirs of Jean du Sirech.

The castle is private property and closed to visitors, so plan to view it only from the public road through Salviac; do not attempt to enter the courtyard or buildings. The 1962 monument historique listing protects the structure but grants no access. The stone spiral staircase and the 18th-century perron on the western logis can only be seen by those admitted by the owners.

The castle is also called "des templiers", though the name comes from the Cazelles family tower, not the Templars. The Gransault-Lacoste family gave the castle its name in the 17th century, and Pierre Gransault de Lacoste bought it in 1780 from the heirs of Jean du Sirech.
