CHIESA DI SAN MARCO (16th century) The Church of San Marco is made up of two churches that are placed one over the other. They were built by the Compagnia della Santissima Trinità dei Laici in 1580 and were dedicated to the Holy Trinity. With the destruction of the old church of San Marco in the 18th century, the present church, which was not too far away, took the title and the name of San Marco. It is the church of the patron saint of the city. It has a single nave in Baroque style designed by Sellari. The canvas on the right side altar is attributed to Commodi and portrays Saint Carlo Borromeo. The Church contained the Lorenzetti crucifix that is now at the Diocesan Museum. The lower church is very beautiful with painted vault ceilings and canvases painted with scenes from the sacred history. On the facade that watches over the valley there is a large mosaic portraying San Marco created by Gino Severini (1883-1966).
