The patron of Massa Martana is Saint Felix, celebrated on 30 October in the church that bears his name, in the old centre.
In the hamlet of Villa San Faustino there is a place that bears witness to how ancient the Christian presence is in this area: the only catacomb in the whole of Umbria, used from the 3rd to the 5th century and already known in the 17th century as the Grotte di Traiano. Explored in modern times, in the early 20th century, by the archaeologist Giuseppe Sordini, it contains more than three hundred burials and descends as much as seven metres below ground level, with a long straight corridor twenty-five metres long.
