Servian Wall
It was built by the Roman consul Marcus Valerius Maximus around 286 BCE and later lengthened to the territories of the Marsi and the Aequi, in the Abruzzo, as Via Valeria. Its total length was approximately 200 km from Rome to Aternum (the modern Pescara). It exited Rome through the Aurelian Wall at the Porta Tiburtina, and through the Servian Wall at the Porta Esquilina.
