Church of St. Ansanus and Crypt of St. Isaac

The church of St. Ansanus was entirely rebuilt at the end of the 18th century by Milanese architect Antonio Dotti.
It features a single nave and keeps a series of interesting works of art, including a fresco by Giovanni di Pietro a.k.a. Lo Spagna portraying Madonna with Child and two saints, a surviving fragment of the bigger pictorial decoration at the “Lombards’ Chapel”, and a canvas by 17th-century painter Archita Ricci from Urbino, placed above the altar and portraying the Martyrdom of St. Ansanus.
The Crypt of St. Isaac is accessible from within the church; Syrian monk Isaac had reached Spoleto in the first half of the 6th century and became the first hermit on Monteluco. During the palaeochristian period, a church was obtained from the previously existing Roman temple, that would later become the crypt of the new church, built after the street level was raised. It features a nave and two side aisles, divided by spolia columns featuring 8th/9th-century capitals and covered by a groin vault. The crypt is decorated by very interesting 11th/12th-century frescoes that underwent detachment and restoration and were finally brought back in situ in 1971.
