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.
