The Pivier d’ Acone , or parish of Acone, is in the Val di Sieve , or Valley of the Sieve, one of the affluents of the Arno. Here the powerful family of the Cerchi had their castle of Monte di Croce, which was taken and destroyed by the Florentines in 1053, and the Cerchi and others came to live in Florence, where they became the leaders of the Parte Bianca .
