Below the town walls at the end of a long cypresses-lined avenue, the church of San Biagio was built from 1518 to 1545 by Antonio da Sangallo the Elder but shows the influence of Bramante. Built of gold-colored travertine to house a much-venerated image of the Madonna, it is considered one of the finest buildings of the Renaissance. Its open and splendidly proportioned interior is on a Greek cross plan, with four arms of equal length and a high dome supported on a drum. Of the two free-standing campaniles, the one on the right is unfinished. The presbytery has 16th-century frescoes depicting the Death, Assumption, and Coronation of the Virgin, believed to be by the Zúccari brothers. On the reredos of the high altar from the same period are four figures of saints. The nearby canónica (priest's house) and its fountain were designed by Sangallo but built after his death. It now houses a small museum devoted to St. Blaise (San Biagio). The late afternoon sun turns the church a golden color, a beautiful sight among the trees.
