Construction system. Vaults of building coverings

The diagram shows the construction system of the vaults.
Those in the basement were shaped on the ground after having made the foundations resting on the “thunder” and the perimeter walls with “rudds”. The vaults of the above ground floors, on the other hand, are built using chestnut wood poles and curved wooden staves as support to give the shape of the vault.

Local names given to the stones according to their size, from the smallest to the largest:

“e pullicine”
“e savurrelle”
“e savorre”
“e mazzacanielle”
“e mazzacane”
“e mezze prete”
