Santa Cecilia in Trastevere
Paschal rebuilt three basilicas of Rome: Santa Prassede, Santa Maria in Domnica, and Santa Cecilia in Trastevere. These churches contain mosaics with lifelike portraits of Paschal. Paschal is credited with finding the body of Saint Cecilia in the Catacomb of Callixtus and translating it to the rebuild the basilica of Santa Cecilia in Trastevere. Paschal also undertook significant renovations on Basilica di Santa Maria Maggiore. In addition, Paschal added two oratories to Old St. Peter's Basilica, SS. Processus et Martinianus and SS. Xistus et Fabianus, which did not survive the 16th century renovation of St. Peter's.
