The Porta Maggiore (ancient Porta Praenestina) in Rome supports the channels of two aqueducts (Aqua Claudia and Anio Novus). Both were begun by Caligula in 38 and finished by Claudius as the topmost inscription records in 52. The lengths given in the text (45 and 62 Roman miles)are the actual lengths of the channels and not the distance from of the sources from the city. The inscription below this records a restoration in by Vespasian, while a third inscription speaks of a second restoration by Titus in 81. It was later repaired by Severus and Caracalla about ,. 200. The gateway is double, with arches that are much more ornate than those in the rest of the aqueduct. Two roads (Via Labicana and Via Praenestina) passed through it.
