: San Gimignano
Volterra is located in the province of Pisa and lies between the valley of Era and Cecina. Built on a hilly Pliocene ridge 545 meters above sea level, surrounded by two defensive walls, one Etruscan and the other Medieval, it is one of the most important centers of Tuscany, for its monuments which testify 3,000 years of civilization and for its traditional craftsmanship in alabaster whose products are one of Italy's leading crafts. Volterra is not yet touched by the stress of contemporary life and visitors who come to Volterra have the immediate impression of stepping into the past, of being in a particular place with its narrow medieval streets and the enigma of its Etruscan origins. Volterra is prevalently medieval and yet cherishes abundant evidence of the Etruscan period: the Porta all'Arco (the Etruscan gate) which date from the 4th century B.C., the Acropolis, and the defensive walls which are still visible in parts of the town.
