Trastevere is the 13th rione of Rome, on the west bank of the Tiber, south of Vatican City, and within Municipio I. Its name comes from the Latin trans Tiberim, meaning literally "beyond the Tiber". Its logo is a golden head of a lion on a red background, the meaning of which is uncertain. To the north, Trastevere borders on to the XIV rione, Borgo.
