The first records date back to 1178 and concern a church dedicated to San Rufino that was considered rather important in the Middle Ages, as the titular saint was one of the patrons of Spello. The church was under the aegis of the abbey of San Silvestro di Collepino, which belonged to the Camaldolese order; at the beginning of the 16th century it became the seat of the Disciplinati di San Girolamo order, which came from the church of Sant’Ercolano, while in 1564 it became the property of the church of Santa Maria Maggiore.
Work was undertaken to reorganize the square at the end of the 16th century and another church was built upon it, initially dedicated to San Rocco and then named after San Filippo when the friars of that order arrived in 1640. Over the years the church underwent some modification, until it was transformed into a Post Office in the 1980s. We can now see only the perimeter walls of the ancient church of San Rufino, in particular the right wall and back wall, which have been incorporated into the Middle School building and the left wall which has become part of the public Swimming Pool; inside you can still see the two naves covered by a cross vault resting on pillars. Signs of the building work that led to the construction of the church of San Filippo remain on the facade of the current Post Office.
