Château de Montluc stands in Estillac (Lot-et-Garonne), in the Nouvelle-Aquitaine region of France. The building is listed as a historic monument (dating recorded in the Mérimée database: 14th century, 16th century). The building is privately owned and no visits are on record.

The château d'Estillac is a fortress built in two phases: its medieval core dates to the 13th century, but Marshal Montluc fundamentally transformed it from 1567 onward into one of France's last military strongholds of that era. The structure features a trapezoidal plan around a central courtyard, flanked by defensive towers pierced with arrow slits and gun ports. This architecture blends the latest 16th-century military innovations, including the bastion that Montluc had tested in Italy, foreshadowing Vauban's later methods. The château preserves notably its 14th-century kitchens and the Marshal's white marble cenotaph, built into the fortification wall.

What to know

The château, classified as a historic monument, was designed by Marshal Montluc as a fortified redoubt intended to serve as a base for military operations.
The kitchens display 14th-century architecture, creating a contrast with the 16th-century defensive innovations that characterize the rest of the building.
The Marshal's cenotaph, made of white marble, is set into the north face of the fortification wall, though partially damaged over time.
