Chiesa di San Francesco is a late-Romanesque- early Gothic architecture, Roman Catholic church located on Via Ippolito Scalza in the southern ridge of the historic center of Orvieto, Umbria, Italy.
It was consecrated as Santi Francesco e Ambrogio in memory of Saint Francis and the Blessed Ambrose of Massa Maritima (died in 1240).
[3] The building is typical of Franciscan churches of the period with a single nave, a quadrangular apse and a trussed wooden roof.
Its high rose windows have been replaced but the sculpted marble portal, with multiple pilasters and ogival arch, survives intact.
[3] The interior originally took the form of a hall church but was redesigned in 1773 when colonnades were added to provide for side chapels.
