Palermo has at least two rings of city walls, many pieces of which still survive. The first ring surrounded the ancient core of the Phoenician city – the so-called Palaeopolis (in the area east of Porta Nuova) and the Neapolis. Via Vittorio Emanuele was the main road east–west through this early walled city. The eastern edge of the walled city was on Via Roma and the ancient port in the vicinity of Piazza Marina. The wall circuit was approximately Porto Nuovo, Corso Alberti, Piazza Peranni, Via Isodoro, Via Candela, Via Venezia, Via Roma, Piazza Paninni, Via Biscottari, Via Del Bastione, Palazzo dei Normanni and back to Porto Nuovo.
