The church of San Cristoforo may be small but it is linked to a great saint, San Francesco (Saint Francis), because it was here that he found 'room for the night' during his stay in Terni in January 1213, as guest of the Dean of the church. There is a tablet to remember Francesco's sermon to the people of Terni, and, just outside the church, the stone upon which he leant during his preachings.
A small building, Romanic, built using the materials found around the site. Probably there was once a pagan temple. Archeological remains were found during the repair works performed on the damage caused by the World War ll bombings: these were friezes, a jellyfish, a stele and a tombstone walled onto the front. All this material dates back to the first centuries after Christ, therefore one thousand years before the church was built. This is said to be the location of a miracle performed by San Francesco, where he turned vinegar into wine when he was invited to dine in the house of a gentleman who had gone to see him. Next to the old church a larger, more modern church has been built, using typical building material to be found in Terni, sponge stone.
On one side San Cristoforo had vegetable gardens to separate it from the church and on the other side the large Camporeali estate opened (owners of the vegetable gardens as well) which ran around all the north west side of the city up to the church of San Francesco. All the area has been named after the family, and is still used in Terni today to refer to the area which includes piazza Tacito, and the square of the Camera di Commercio building. Camporeale was a piece of farmland which was inside the medieval city walls, with a stream which fed mills and irrigated the crops of a land planted with trees and ploughed. The little church of San Cristoforo, therefore, was on the land of the Camporeale's, who had descended into Italy in the wake of Federico Barbarossa, who held the ius presentandi, that is the right to choose the parish priest who was then presented to the Bishop who then officially decreed the official nomination.
