The troglodyte world of our region is unique because of its nature. Contrary to caves which were used in prehistory for accommodation, our caves were originally dug out for their raw material, particularly ‘tuffeau’ stone (known as ‘Bourré stone’).
Soft and porous, this rock was extracted from the Loire hills and has been used since the Middle Ages in the construction of houses, religious buildings, fortified towers and chateaux.
It was the work of quarrymen also called perriers who tore off the stone from the rock walls using a pick. A tough job, paid by the piece.
The stone blocks were then transported by boat along the Loire and Cher rivers.
