The church of Santa Maria in Trastevere is claimed to be the oldest church dedicated to the Virgin Mary in Rome. A basilica was built here in the 3rd Century CE, but the present church dates from the 12th Century; the rich interior was redecorated during the Baroque period. Inside the church are a number of late 13th-century mosaics by Pietro Cavallini on the subject of the Life of the Virgin (1291) centring on the “Coronation of the Virgin” in the apse.
