The Porta Latina (Latin - Latin Gate) is a single-arched gate in the Aurelian Walls of ancient Rome. It marked the Rome end of the Via Latina and gives its name to the church of San Giovanni a Porta Latina. Most of the present structure dates to Honorius, including the arch's voussoirs (though they are often wrongly attributed to a 6th-century restoration by Belisarius, due to a cross and circle sculpted on the inner keystone, and the Chi Rho between Α and Ω sculpted on the outer keystone). The gate retained its name throughout the Middle Ages. Also nearby are the oratory of San Giovanni in Oleo and the pagan Columbarium of Pomponius Hylas.
