San Vittore alle Chiuse is an ancient Romanesque church located in Genga, in the Marche region of Italy. The church is situated in a narrow gorge in the Apennine Mountains, and it is believed to date back to the 11th century. The church is dedicated to Saint Victor, who was a Christian martyr of the 3rd century.

The name "alle Chiuse" refers to the narrowness of the gorge in which the church is located, which gives the impression of a "closed" space. The church has a simple, rectangular plan with a single nave and apse. The exterior is characterized by its simple stone walls and a bell tower with a square base and a cylindrical top.

The interior of San Vittore alle Chiuse is notable for its beautiful frescoes, which date back to the 13th and 14th centuries. The frescoes cover the walls and vaults of the nave and apse and depict scenes from the life of Christ, the Virgin Mary, and the saints. The frescoes are considered to be some of the finest examples of Romanesque art in Italy.

San Vittore alle Chiuse is a popular destination for tourists and pilgrims who come to admire the church's unique location and beautiful frescoes. The church is also a popular venue for classical music concerts due to its excellent acoustics.
