 The gate by which it left the Servian walls of Rome bore the name Porta Capena; perhaps the only case in which a gate in this line of fortifications bears the name of the place to which it led.At what time the Via Latina was stretched to Casilinum is doubtful (it is quite possible that it was done when Capua fell under Roman supremacy, i.e.before the construction of the "Via Appia"); it afforded a route only longer, and the difficulties with its construction were much less; it also avoided the troublesome journey through the Pontine Marshes.
