Sant'Anna Caves - Castelfidardo
The underground tunnel complex of Castelfidardo probably dates back to between 1300 and the second half of the 1400s; these would have functioned as cellars, warehouses, seasonal homes, temporary shelters (especially in case of danger) and communication routes with the outside of the castle and between its sides.
