Origin and history

The Cluzeau de Chambrebrune, classified as a Historical Monument in 1988, is a troglodytic site dug and built between the 10th and 12th centuries near Brantôme, Dordogne. This set spans 45 metres long and two levels, combining natural cave and human resizes to form defensive habitat. The main access, to the northwest, includes a shelter terrace and a corridor with murderers facing the outside, while a door with a closing system reinforced security. A second entrance, on the ground floor, incorporates a trap pit and side murderers to neutralize the intruders.

The first floor, accessible by a rock-cut staircase, houses an upper room equipped with eight grain elevators, a water supply, and storage niches. Defensive features — successive doors, deadly, and a narrow corridor — protect this space, while windows allowed watchmen to monitor the surroundings. The narrow terminal gallery ends with a final murderer, illustrating the ingenuity of the medieval defense systems adapted to a karst relief. The whole reflects an organized human occupation, mixing daily life (storage, habitat) and protection against external threats.

The location of the site, near Brantôme, a strategic area in Périgord, suggests its role in a network of territorial defence or control during the Middle Ages. The layouts — silos, benches, and closures — demonstrate rigorous planning to ensure the independence and safety of occupants. Enrollment in the Historical Monuments in 1988 highlights its heritage value, both architectural and historical, as a remarkable example of medieval troglodytic architecture in New Aquitaine.
