Roman Villa on the Via Clodia was built at the end of the second century A.D. There now are the remains of a three-story building, about 18 m high, concrete with brick cladding. There are arched openings to the outside and inside of the building has a central courtyard. On the side covered corridors retain traces of marble covering the walls. Nearby a cistern is preserved. In medieval times it was a 'domusculta', a papal farm, and in the ninth century it was used as a church dedicated to St. Stephen of which remains an apse built in striped unusually regular work. In the mid nineteenth century the building was used as a cemetery in conjunction with outbreaks of malaria.
