The church dedicated to S. Montano dates back to the twelfth century and played an important role in the thirty-six years spent by Rita in Roccaporena. Here she received her first religious instruction, here she went to attend Mass and other celebrations, here she married Paolo di Ferdinando. According to tradition, Montano came to Porena from distant Lycia (Asia Minor) to preach the Gospel. However, a manuscript chronicle, preserved in the Municipal Library of Perugia, informs that he was part of the group of Syrian hermit monks who settled in the Castoriana Valley, at the time of the Saints Spes and Eutizio.
S. Montano died in Roccaporena with a reputation for holiness; the people proclaimed him his protector and named him the parish church. The current construction is the result of various renovations: the oldest church was a single nave, corresponding to today’s left; in the fourteenth century the right aisle was added.
Cascia is located in Valnerina just 20 km from Norcia.
