Rocca di Urbisaglia -  Macerata, Marche The fortress is much later than the fortified borough, since it was built in the early sixteenth century by the city of Tolentino, occupying the site of a preexisting medieval circle possibly on the very site of the Roman Arx (fortress) of Urbisaglia.

The fortress, surrounded by a ditch, enclosed also the ancient 12-th century tower, one of the many sighting towers common in the early Middle Ages.
