The church is located along the city's main street and its structure is reminiscent of the simplicity typical of mendicant orders.
The Gothic-style façade is enriched by the slender ogival portal, with bundles of small columns and rich capitals and a highly original rose window. Another small side aisle was added to the single-nave structure, initially open to the street and used as a covered market, later closed. In 1466, on the other side, the convent cloister was built, which is of beautiful workmanship and today houses many initiatives for territorial promotion.
The vault of the nave has an exposed wooden truss roof and ends with a polygonal apse, where the altar, raised three steps, is located.
Inside, there are numerous traces of frescoes from the Umbrian and Tuscan schools, dating from the late 13th century to the 17th century. Of particular interest among these is the Coronation of the Virgin between Angels and Saints, a fresco attributable to the Sienese school. Important is the 15th-century frescoes of the Umbrian school.
It should be noted that the iconographic reference to St Chiara della Croce returns several times, such as to the right of the main door, below. Inside the church, the "mortal remains" of the Blessed Chiarella and Illuminata are preserved in a reliquary on the right aisle. Further along the same wall, again in a wooden reliquary, is the mummified body to which the Legend of the Blessed Pellegrino of Montefalco is linked. Legend has it that it is the body of a 14th-century pilgrim who reached Montefalco from Spain to venerate the body of Blessed Clare. When evening arrived, he asked the friars for hospitality and before going to rest he returned to the church, where in the morning, the sacristan sitting at the confessional found him, dead, in the same position in which we can still see him. He was buried but was found outside the tomb and the episode was repeated in the following days. So it was decided to place him in the bell tower, where he remained for a hundred years without the body decomposing. The Fathers then had him placed in the Sacristy, in a glass case in the same pose and with the same pilgrim's clothes he was wearing.
