The small Italian island of Capri is situated 5 km from the mainland in the Bay of Naples, a celebrated beauty spot and coastal resort since the days of the Roman Republic until now. It is also part of Campania.
Capri, known in Greek mythology as the isle of the sirens, was a favored resort of the Roman emperors. Most notoriously, the emperor Tiberius had his villa on the island, the location (supposedly) of debauched orgies. Those who displeased the emperor were flung to their deaths from the cliffs. The island is world famous and is very touristy, especially when swamped with tourists in July & August, but other times of year it is calmer and more relaxing.
