Bassano Romano is a town and comune situated in the hills of Monti Sabatini in the province of Viterbo, in northern Lazio.
With its origins about 1000 as the agricultural hamlet of Bassano di Sutri the village's future was founded in 1160 by the wealthy landowner Enotrio Serco, who initiated the construction at the top of the slope of a fortified residence that over the centuries became a princely dwelling, frescoed by famous artists. In 1482 Pope Sixtus IV assigned the Foedus Bassani to the Anguillara, Roman patricians. The growth of the comune redoubled after 1565, when the signory was reassigned by Pope Clement VIII to the Giustiniani, merchants of Genoese origin settled at Rome. In 1605 the signory was raised to a marquessate: a hunting lodge called "La Rocca", granaries, a stone bridge and the church dedicated to San Vincenzo were all constructed. During the Giustiniani residence, artists were commissioned to carry out frescoes: Francesco Albani, Domenico Zampieri "Domenichino" and Antonio Tempesta are all represented.
