The "Borgo Nuovo" (Monte Romano) was built as a model farming town at the beginning of the 1600s and is the result of a compromise between baroque architecture and a farming community's practical needs.

Coming from the South-West (Tarquinia), just after the town gate on the left is the Granaio Agucchi (grain store). On the other side of the road is the elegant town centre with the Rocca Nuova, the Chiesa Vecchia, the Fontana del Mascherone, the Torre dell'Orologio (clock tower, with prison cells below) and the "Case in linea" nearby (built using an innovative mass housing construction technique for those times).

The centre of town has no fewer than four interconnected squares, on several levels, creating a wide open space with a very Italian feel to it: Piazza Dante, Piazza dello Statuto, Piazza Plebiscito and Piazza XXIV.
