The Abbey of Sassovivo was founded in the year 1000 and restored during the 1800s. There is a beautiful cloister here of 1229, designed by Pietro di Maria, who was assisted by Nicola Vassaletto. The paired columns (158 in all) and the 58 arches were sculptured in Rome and transported here along the Tiber and then across land from Orte, and are said to compare with those of I Santi Quattro Coronati, in Rome. The abbey also owned the castle at Scopoli - on the way to Colfiorito.
