 Boville Ernica was once situated on the plains below its present site, but after the Saracen and Hungarian invasions (9th–10th centuries), its population moved to the higher levels of Monte Fico, where the ancient center was transformed into one of the most fortified towns in the region.In addition to the Pelasgic walls, sights include the castle and its Medieval walls having as many as 18 turrets and towers (alternating as round and square shapes), all standing completely intact.Boville is also home to many Renaissance palaces and churches.
