Colle di Val d'Elsa, locally known simply as Colle, stands on the oldest part of a hill a few miles from San Gimignano and Monteriggioni. Straddling the ancient Via Francigena, it has always been a thoroughfare for pilgrims and travellers, who would stop here to rest beneath its distinctive tower-houses. These constructions rise up right across the town: no longer inhabited, they nevertheless contribute to the unique urban profile. One of these towers is famous for having been home to the artist Arnolfo di Cambio, sculptor, architect and student of the influential Nicola Pisano.
