Hidden behind a colourful patchwork of warped homes, this low-slung, wood-beamed, delightfully uneven medieval walkway dates to 1290. It's unique in Italy because it began life as a defensive wall that was later incorporated into the town's commercial space (as an elevated pathway for donkeys carrying gypsum from nearby quarries). Today, former donkey stables now hide private homes (and one dental office) that sit atmospherically along 100m of picturesque, non-uniform arches, flanked by at least one surviving guard tower.
