The quay most cruise passengers step onto was named for a dynasty that ruled Naples from 1266: Molo Angioino, the Angevin pier. The terminal address, Molo Angioino, 80133 Napoli NA, Italy, sits barely 400 metres from Piazza Municipio and the walls of Castel Nuovo. That proximity is the whole premise of the naples walking tour from cruise port — a city whose historic core begins where the mooring lines end. Naples was founded as Neapolis, the "new city," by Greek settlers from Cumae around 470 BC. Its grid survives. The three parallel decumani and the narrow cardines still cut the centro storico, and Spaccanapoli — the straight slash of Via Benedetto Croce and Via San Biagio dei Librai — follows the lower decumanus almost exactly. Walk it and you are tracing a Greek surveyor's line laid down two and a half millennia ago. UNESCO inscribed the historic centre on the World Heritage list in 1995, citing this continuity of plan across twenty-seven centuries. What accumulated on that grid is unusually dense. Castel Nuovo, begun in 1279 for Charles I of Anjou, carries a white triumphal arch inserted in the 1450s for Alfonso of Aragon. The Galleria Umberto I, finished in 1890, roofs its crossing with iron and glass. Via San Gregorio Armeno has sold nativity figures since the eighteenth century. Beneath the Duomo lie Greek walls and a Roman market; beneath the whole city run some 450 kilometres of quarried tunnels and aqueduct channels, cut from the soft yellow tuff the buildings above are made of. Vesuvius closes every southward view, 1,281 metres high and nine kilometres from the waterfront. The city matters today partly because it refused tidiness. Churches sit on temples, Baroque cloisters open off streets of scooters, and the Cappella Sansevero holds Giuseppe Sanmartino's Veiled Christ of 1753, carved so that marble reads as cloth. Guided naples walking tour from cruise port tours exist because the layers are legible only with help: a façade on Via dei Tribunali may hide a fourteenth-century chapel, and the paving underfoot is often Vesuvian basalt cut into squares. Entry to the streets themselves costs 0 EUR, free entry for public walking routes through the city streets, which makes the naples walking tour from cruise port less a ticketed attraction than an inhabited archaeological site, open 00:00–23:59, every day of the week, as it has been since the Greeks drew the first line.
