Trevi nel Lazio, Province of Frosinone, Lazio

Trevi nel Lazio (in Antiquity, Treba Augusta), is an ancient town in the upper valley of the Aniene river. It is 17 km by road NE of Fiuggi and 23 km (14 mi) by road SE of Subiaco, the nearest larger towns. An old arch within the territory of the comune is said to be Roman, and some remains of the ancient acropolis have survived, but otherwise Trevi's monuments are medieval.

The town first makes its appearance as Treba, a place of the Aequi, and later was called Treba Augusta to help distinguish it from Trebiae (Trevi in Umbria). The town was a bishopric from 499 to 1060; in the 15th century, it was sacked by Alfonso V of Aragon.

What to see

  • The church of Santa Maria Assunta
  • Oratory of San Pietro (the St. Peter in question is not the apostle, but a local hermit)
  • Oratory of Santa Maria del Riposo, with 15th-century frescoes.
