Château de Nadaillac-de-Rouge, Medieval castle in Nadaillac-de-Rouge, France.

Château de Nadaillac-de-Rouge is a medieval castle in the Lot region that showcases construction elements spanning multiple centuries. The main residential block and substantial side wings date primarily to the 17th century and form the core of the current structure.

The castle was rebuilt following the Hundred Years War on its original foundations, marking a recovery after medieval conflicts. Inscriptions on the south buildings indicate construction activity dating to 1711.

The property remains in the hands of the Marquises de Nadaillac family, representing centuries of continuous aristocratic ownership in the Lot region.

The château is privately owned and not open as a public museum, so visits must be arranged with the owners in advance. It was fully restored between 1968 and 1973. The building stands in the commune of Nadaillac-de-Rouge in the Lot département; the entrance is reached by steps through a low retaining wall to a double white door.

The château has belonged to the Pouget de Nadaillac family for a long time and is still a hereditary property of the Marquises de Nadaillac, who also owned the Château de Lalande. It was listed as a monument historique on 10 May 1999. The south buildings carry the date 1711, and the whole château was restored between 1968 and 1973.
