Nerola is a town and comune of the Metropolitan City of Rome, Latium, Italy. Name The name Nerola is probably derived from the Sabine word nero or nerio, which meant "strong" and "brave". The inscription on the fountain in the piazza of the town hall A Nerone tuum Nerola nomen habet traces the origin of the name back to the Roman emperor Nero, who belonged to the gens Claudia, which had distant Sabine origins. Traces of a Roman era villa have been found on that site, which legend attributes as belonging to Nero himself. History Acquaviva Within the comune is the frazione of Acquaviva, on the ancient Via Salaria. This may have been the seat of the bishopric called Aquaviva in Latin, whose bishops took part in synods held in Rome in the second half of the 5th century and the beginning of the 6th: Paulus or Paulinus in 465, Benignus in 487, 497, and 502, and Bonifacius in 503. No longer a residential bishopric, Aquaviva is today listed by the Catholic Church as a titular see. Castello Orsini di Nerola In the second half of the 10th century, the castle Castrum Nerulae was founded by the "Sabine chancellor" Benedetto Crescenzi, and the Crescenzi family held it until 1235, when it came under the direct control of the pope. At the end of the 12th century, the fiefdom was granted to the Orsini family, who built the present Castello Orsini. At the end of the 15th century, the castle was subsequently reinforced with strong towers and other defensive fortifications around the village. Near the castle, the chiesa vecchia (Old Church) was built in 1483. In 1644, the castle and the territory of Nerola were yielded to the Barberini family along with the Montelibretti family and, in 1728, entered into possession of the Sciarra clan, and thence to the Lante della Rovere family, who founded the charitable institution of the Ospedale dei Pellegrini to assist travellers on the Via Salaria. In 1867, the castle was occupied by a contingent of partisans of Giuseppe Garibaldi who were fighting against papal troops. Since passing to Marquis Ferrari-Frey in 1939, the castle has been restored and now houses a hotel.
