Of the hundreds of towers for which medieval Bologna became famous, fewer than 20 remain, and these two are the best known, thought to be named after the families which built them as part of a centuries-ago display of power and wealth, and now unmistakable symbols of the city. The Torre di Asinelli is open to visitors, and you can climb to the top of its 98-metre (322-foot) height - keeping in mind that the climb can be dark, cramped, and otherwise challenging. But at the top, you'll be richly rewarded with an awesome view over most of Bologna - and on clear days, even out to the Adriatic Sea.
