Naples is the capital of the Italian region Campania and the third-largest municipality in Italy, after Rome and Milan. In 2015, around 975,260 people lived within the city's administrative limits. The Metropolitan City of Naples had a population of 3,115,320. Naples is the 9th-most populous urban area in the European Union with a population of between 3 millions and 3.7 million. About 4 million people live in the Naples metropolitan area, one of the largest metropolises on the Mediterranean Sea.
Naples is one of the oldest continuously inhabited cities in the world. Bronze Age Greek settlements were established in the Naples area in the second millennium BC. A larger colony – initially known as Parthenope, Παρθενόπη – developed on the Island of Megaride around the ninth century BC, at the end of the Greek Dark Ages. The city was refounded as Neápolis in the sixth century BC and became a lynchpin of Magna Graecia, playing a key role in the merging of Greek culture into Roman society and eventually becoming a cultural centre of the Roman Republic. Naples remained influential after the fall of the Western Roman Empire, serving as the capital city of the Kingdom of Naples between 1282 and 1816.
Spaccanapoli is the straight and narrow main street that traverses the old, historic center of the city of Naples, Italy. The name is a popular usage and means, literally, "Naples splitter". The name is derived from the fact that it is very long and from above it seems to divide that part of the city.
This street is the lower (Decumanus Inferiore) and southernmost of the three decumani, or east-west streets, of the grid of the original Greco-Roman city of Neapolis. The central main Decumanus Maggiore is now Via dei Tribunali; while the northernmost or upper Decumanus Superiore is now via Anticaglia and Via della Sapienza. The three decumani were (and still are) intersected by numerous north-south cross-streets called cardini, together forming the grid of the ancient city.
