Naples's historical centre has been included by the UNESCO in the World's Heritage of Mankind; with its historical witnesses spanning across 2.500 years, it is provided with 20 museums, 4 huge picture-galleries, the Aquarium, the Botanical Garden, 4 castles, 5 city gates, 2 royal palaces, 6 parks, many historical fountains and squares, 7 libraries, a huge number of monumental streets and buildings, over 100 churches and catacombs of remarkable historical value. The archaeological inheritance is relevant, and is sometimes part of the urban structure. Naples can be righteously considered a city of Art, Handicraft, Folklore, Music, Culture, Science, Cuisine. its Origins mount back to Greek colonisation, and its history has never been interrupted since then. Once chief town of a kingdom, it now offers many different itineraries to the visitor: the Greek-Roman, the Renaissance, the Fountains', the Caravaggio itinerary and others. Naples is like a casket to be opened street by street, square after square, monument by monument, so that you can keep memories of it that'll never fade.
