Origin and history

The Château de Lacoste, located in Salviac in the Lot, finds its origins in a primitive castrum founded by the barons of Gourdon in the 10th or 11th century. Few remains remain of this first enclosure, but the tower of the Cazelles, probably erected in the 13th century by a vassal knight, marks the location of the old fortification. This site, originally linked to templars, becomes a noble house before being remodelled over the centuries.

In 1226 Bertrand de Gourdon, then his son Guillaume in 1246, paid tribute to the Count of Toulouse for the fief of Salviac. The seigneury then passed into the hands of influential families: the Malemort (13th century), the Balenes (1310), then the Cazetons, who became Barons of Salviac before 1387. From 1438, the baronie returned to the Durfort-Boissières, which kept it until the Revolution. The strong house, occupied by the Sirech in the 16th century, was then transformed with the addition of a circular tower and wings into square.

In the 17th century, the Gransault de Lacoste family, the Durfort property manager, acquired the castle in 1780. The monument, which now bears their name, preserves medieval elements and woodwork of the seventeenth century. In 1962, he became a member of the historical monuments, testifying to the architectural and seigneurial evolution of Quercy, from templars to local noble families.

Today, the castle consists of three housing bodies organized around a courtyard, supplemented by a fourth more recent building. A stone screw staircase dating back to the 15th and 16th centuries serves the different levels. The 18th-century layouts, such as the large western porch, reflect the successive adaptations of the site, mixing medieval heritage and classical modifications.

Historical sources, including the work of Catherine Didon and Colette Chantraine, highlight her role in the Barony of Salviac. The castle also illustrates the feudal dynamics of Quercy, between family alliances (Gourdon, Malemort, Durfort) and architectural transformations, from Templar fortifications to the aristocratic residence.
