First remember the five village names
Cinque Terre is in northwest Liguria, on a stretch of coast west of the province of La Spezia. The 'five' are Monterosso, Vernazza, Corniglia, Manarola and Riomaggiore, lined up from northwest to southeast. The coast, the five villages and the hills behind together form a national park, listed as World Heritage in 1997.
Documents of the eleventh century already mention this area. The first settlements were Monterosso and Vernazza, then under the Republic of Genoa; the other three villages grew later. In the sixteenth century residents strengthened old forts and added watchtowers against sea raids.
From the seventeenth to nineteenth centuries the area slowly emptied, until La Spezia built its arsenal and the railway reached Genoa and revived it. The railway also carried people out, and traditional livelihoods declined; from the 1970s, as visitors grew, the villages grew lively again.
