Naples

Naples is one of Europe's oldest continuously inhabited cities, layered with Greek, Roman, Norman, Aragonese, and Bourbon history compressed into a dense historic center that UNESCO has protected as a single monument. Underground Naples, accessible through multiple archaeological tunnels and cisterns, reveals Greco-Roman streets and World War II shelters beneath the modern city. The National Archaeological Museum holds the world's foremost collection of Roman-era art and artifacts, including complete decorative programs transferred from Pompeii and Herculaneum.
