Set amid some of the most dramatic coastal scenery on the planet are the five villages of the Cinque Terre. Rooted in antiquity, Cinque Terre's five villages date from the early medieval period. Monterosso, the oldest, was founded in AD 643, when beleaguered hill dwellers moved down to the coast to escape from invading barbarians. Riomaggiore came next, purportedly established in the 8th century by Greek settlers fleeing persecution in Byzantium. The others are Vernazza, possibly the most beautiful, Corniglia and Manarola.
