The historic centre, surrounded by walls fortified with
ramparts with cylindrical crenellated towers and arches, is grouped around the
parish church of Sant'Andrea, which has an eighteenth-century
appearance. Inside it are a panel of 1478 by Carolino of Viterbo (Madonna
enthroned and Child) and two canvases by Gabriele di Francesco (St.
Andrew and St. Věctor). The church of San Vittore, already in
existence at the end of the fifteenth century and subsequently reorganised,
has an outstanding eighteenth-century wooden coffered ceiling.
A short way outside the town along the road to Fabrica di
Roma is the noteworthy church of Santa Maria del Ruscello, built in
1604 to a design by Vignola drawn up several decades earlier. The edifice is
preceded by a short, wide avenue. The facade, with two superimposed floors
surmounted by an elegant dome refined with a charming little lantern, has a
fine walnut portal, with reliefs of figures and grotesques: the Annunciation,
the Visitation, St. Victor on horseback and St. Andrew the
apostle. The interior has a single nave with four altars decorated with
admirable Baroque stuccoes, and houses a seventeenth-century canvas by
Lanfranco (Madonna in glory with St. Barbara and St. John the Evangelist), several
frescoes by Vandi, a wooden Crucifix of the seventeenth century, a fresco of
the Latium school (Madonna del Ruscello) and a monumental organ by the
Vibani brothers dating to the seventeenth century.
