Explore the village of Rochmenier which consists of 250 underground rooms, excavated out of the rock and distributed over around 40 farms. Rooms were added to meet the needs of a growing population. The oldest habitation apparently dates from the 13th century. The village gradually expanded right up to the 19th century. The dwellings are excavated from sandstone which contained sea shells. This rock is a kind of calcareous sand and was used by farmers to neutralise soil acidity. During your visit you will see part of the village consisting of two farms which were abandoned towards the beginning of the 20th century and opened to the public in 1967. The exhibits, furniture, tools and photographs describe the lifestyle of the last inhabitants.
