The Maison des Rochers is located in the hamlet of Graufthal in the Eschbourg commune of the department of Bas-Rhin.
These three semi-troglodyte rock houses were restored and refurbished with furniture and mementos of the past in 1958.
They were included in the supplementary inventory of historical monuments in 1988.
Today they are maintained by an association dedicated to their development, and are open to visitors.
