Origin and history
The castle of Bonas, located in Gers in Occitanie, has its origins in a seigneurial line originally vassal of the kings of England, then of the Counts of Armagnac. The family of Pardailhan began its reconstruction at the beginning of the 18th century, marking the passage from a medieval fortress — which remains the base of the dungeon in the cellars — to a classical residence. The building, of quadrangular plan, is erected directly on the rock, integrating feudal remains with more modern architecture.
In the 19th century, the castle was enlarged and embellished in a classic style, while Antoine de Melet developed outbuildings, including a distillery and communes surrounding a cedar alley. The terrace, supported by an orangery vaulted in a cradle, and the interiors — Louis XIV staircase, portico halls, Louis XV woodwork and painted panels — bear witness to this architectural and decorative evolution.
The ensemble, classified as a Historical Monument in 1976 for its facades, roofs, and interior decorations (stairs Louis XV, room of Caesars, library), illustrates the transition between medieval heritage and refinement of classical centuries. The park and cellars, where the rock stands, recall the original strategic settlement, while the 19th-century developments reflect the adaptation to the tastes of the era.
