Manoir de la Touche-Carné, 15th century manor estate in Val d'Oust, France.

Manoir de la Touche-Carné is a manor in Val d'Oust, in the Roc-Saint-André area, whose buildings are arranged around a rectangular courtyard. The main residence, on the west side, ends at the northeast with a polygonal staircase tower. A small wing with the cellar and kitchen adjoins its west facade, and a long 15th-century outbuilding closes the courtyard to the north.

Built in 1440 for the Carné family, this manor remained under their ownership until 1638 when it passed to the Rogier family of Crévy. This transfer reflected changing patterns of land ownership among Breton noble families during the early modern period.

The ground floor of the main building once functioned as a courthouse for local nobility, showing how medieval lords managed their territories from home. This judicial role shaped the way rooms were organized and how people moved through the space.

The manor sits roughly 2 kilometers northeast of Roc-Saint-André town center and opens to visitors during European Heritage Days in September. It is advisable to check in advance whether the property offers access at other times or if guided visits are required for entry.

The polygonal staircase tower, built in 1380, is the oldest part of the manor. It probably once led to a wing perpendicular to today's main house, which has since vanished. In the 20th century the main house held the hamlet's first telephone, a public phone booth.
