The chestnut has always been very important for Colognora as it represented, until recent times, one of the main means of support in the Roggio Valley. The exploitation of the chestnut provided food and firewood, as well as wood for building and making tools and furniture; the leaves of the tree were used for feeding cows or, dried, in the stables for the animals to lie on.
Besides the processing cycle of the chestnut, other activities, like that of the woodcutter, carpenter, charcoal burner, cooper and housewife, all connected with its exploitation, are presented in the seven rooms arranged on three floors. Together with the museum, it is also possible to visit the village and its surroundings, in particular the so called "metato" where the chestnuts were left to dry and the charcoal pit, a dome shaped construction made of many pieces of wood and covered with wet leaves, earth and turf that lies along a marked path in the woods: it was used to make charcoal from soft (chestnut) or hard (oak or beech) wood sorts.
