Bassano Romano is a town and comune located in the hills of Monti Sabatini within the province of Viterbo in northern Lazio, Italy. The settlement originated around 1000 as an agricultural hamlet known as Bassano di Sutri before being founded in 1160 by landowner Enotrio Serco. Its historical development was marked by various papal assignments and noble ownerships, including the Anguillara family and later the Giustiniani merchants of Genoese origin.
The town is characterized by its princely dwelling, which features frescoes by renowned artists such as Francesco Albani, Domenico Zampieri "Domenichino," and Antonio Tempesta. Significant architectural developments occurred in 1605 when the signory was raised to a marquessate, leading to the construction of the hunting lodge "La Rocca," granaries, a stone bridge, and the church of San Vincenzo. Additionally, the town became a site for the maiolica manufactory of Bartolomeo Terchi in 1735.
