Bagno a Ripoli, Scandicci, Sesto Fiorentino, Calenzano, Signa and Lastra a Signa are now the hinterland of Florence, but each of them shows the vestiges of the past. Scandicci, its hills and the Castello de' Acciaiolo; Bagno a Ripoli at the gate of Chianti; Sesto Fiorentino and its Medicean residences; Campi Bisenzio and the medieval keep; Calenzano and the massif of Monte Morello; Signa and Lastra a Signa along the Arno River, with castles and traditional factories. These are not just suburbs.
