Have you ever heard of the Graufthal Rock Houses? I had already admired these troglodyte houses nestled at the foot of the pink sandstone cliffs from the outside one day but had not yet had the opportunity to visit them. Yes, these incredible blue houses can be visited and it is really worth it!

Where to find troglodyte houses in Alsace?

You will find amazing troglodyte houses that can be visited in Graufthal, in the north of Alsace, not far from La Petite Pierre, in the Vosges du Nord Regional Nature Park.

Visit of the “Maisons des Rochers” in Graufthal near La Petite Pierre

The visit to the Graufthal Rock Houses takes us back in time… But not as far back as one might imagine, since the last one was inhabited until 1958 by Catherine Ottermann. It’s not that old!

The visit allows to discover the history of the place and the inhabitants who lived there, but also to visualize how the houses were arranged. Photos have indeed allowed us to reconstruct the interior of the houses with the antique furniture that was installed.

Even if the layout seems quite nice today, one can imagine how much the living conditions must have been difficultThe house was very cold, both because of the dampness of the rock, the low luminosity and the total absence of modern comforts for a dwelling house… For example, we used to fetch water from the fountain below. We also learn that entire families, and even animals, lived in these small spaces! I heard it wasn’t easy to get the cows in, by the way 😉

Surprisingly, this is also where matches were made in absolutely dantesque conditions… You just have to read the testimonies on the panels of the permanent exhibition to get the full measure of it.

Unique troglodyte houses in Alsace

One can also observe more closely how the troglodytic houses are totally integrated into the imposing pink sandstone walls typical of the Northern Vosges. Indeed, the rock forms the ceiling, the floor and part of the walls of the houses. This is one of the reasons why they were built there: there were only a few walls left to install, making the cost of the house very low… These constructions are really amazing and unique in Alsace.
