Sant'Agata in Trastevere is one of the churches of Rome, located in the Trastevere district, at Largo San Giovanni de Matha, 91. The church is dedicated to the Sicilian St Agatha, martyred in approximately 251, whose cult soon spread well beyond Sicily. She is one of several virgin martyrs who are commemorated by name in the Canon of the Mass. Agatha is also depicted in the famous mosaics of the church of Sant'Apollinare Nuovo in Ravenna, where she appears, richly dressed, in the procession of women martyrs along the north wall.
