Pope Paschal I (Latin: Paschalis I; died 824) was the bishop of Rome and ruler of the Papal States from 25 January 817 to his death in 824.
Paschal was a member of an aristocratic Roman family. Before his election to the papacy, he was abbot of St. Stephen's monastery, which served pilgrims. In Rome in 823 he crowned Lothair I as Holy Roman Emperor. He rebuilt a number of churches in Rome, including three basilicas.
Santa Cecilia in Trastevere (Italian: Basilica di Santa Cecilia in Trastevere) is a titular church and minor basilica located in Trastevere, Rome. Dedicated to Saint Cecilia, the patron saint of music, it has served as a cardinal titular church since the 5th century. The present basilica, rebuilt under Pope Paschal I in the 9th century, is notable for its apse mosaic, frescoes by Pietro Cavallini, Baroque sculpture, and the revered relics of Saint Cecilia preserved beneath the high altar. Today, it remains the conventual church for the adjacent Benedictine abbey, and the feast of Saint Cecilia on 22 November continues to draw pilgrims, choirs, and musicians from around the world.
