A heavyweight Renaissance art city peppered with colossal palaces and still ringed by its intact medieval walls, Ferrara jumps out at you like an absconded Casanova (he once stayed here) on the route between Bologna and Venice. But, like any city situated in close proximity to La Serenissima ('The Most Serene' Venetian Republic), it is serially overlooked, despite its Unesco World Heritage status. As a result, Venice avoiders will find Ferrara's bike-friendly streets and frozen-in-time palazzi relatively unexplored and deliciously tranquil.
