A complete panorama of cave dwellings in the Loire valley. Thanks to detailed researches in unknown sites, the author tried to make a reconstruction of the everyday life of the men who work or live in cave dwellings, quarries or mushroom beds.

Illustrated by new photographs, the main chapters are about underground quarries, cave dwellings, underground refuges, mushroom beds, art in quarries, and also flora and fauna.

The book shows the existence of a real "troglodytic civilisation" in the Loire valley.
