One of the most important archaeological ruins in Italy, probably had its origins as a rest stop and watering place for travelers, traders and soldiers, but most historians fix the town's official founding to about 300 BC. Carsulae's growth into a major town only took place, however, with the building of the ancient Roman road, the via Flaminia, in 220-219-BC.

This interesting archaeological site, located between Terni and Sangemini, has not been completely excavated.

Yet you can see the Forum area with the remains of the cathedral and two twin temples, the Theatre and amphitheatre, both well preserved.

The beautiful St. Damian Arch and, further on, the interesting sepulchral monuments. Just next to the Forum the beautiful St. Damian mediaeval church was built with archaeological stones from the area.
