In the town of Civitavecchia is a small hill (altitude 215 m A.M.S.L) called Poggio Sferracavallo. This hill was artificially modified for the construction of a Roman villa. The villa is bordered to the north-west to the nearby baths of Acque Tauri and south to the Taurine baths (known as the Baths of Traiano).
The structure was discovered in 1939 by S. Bastianelli and underwent a series of surveys by the superintendent SAEM until 1987. The plant perimeter of the building is a square of side 14 m and covers an area of 2000 mq. Dry stone walls in large blocks of sandstone (type Macigno) are the foundations on which the building was built. On the west side there is a wide staircase leading to a basement ever excavated. On the north side of the perimeter walls have a semi-circular base (possibly an apse). On the ground there was a mill and a small oil sump in local sandstone (known as scaglia). The survey shows surface clay fragments of roof tiles, ceramic black-painted, ceramic Italian sigillata and clear. We can say that this is a country house inhabited continuously since I sec.B.C. to V sec.A.D.
