ROCCA

Rocca

Rocca is an Italian term meaning a high, fortifiable stronghold, usually located in smaller towns, beneath or on which the village or town clustered, within which its inhabitants might take refuge at times of trouble; under its owners' patronage the settlement might hope to find prosperity in better times. A rocca might in reality be no grander than a fortified farmhouse. A more extensive rocca would be referred to as a castello.
