If fairy tales had architects, they might"ve come up with something like Alberobello in Italy. But instead of magic wands, it was limestone, mortar-free masonry and—according to some theories—a bit of tax evasion that built this town"s signature homes: the trulli. These are whitewashed stone houses topped with dry-stacked limestone roofs shaped like upside-down ice cream cones. It"s an ancient building technique, and in this case, a clever one. Alberobello"s trulli aren"t hidden one-offs. Entire districts—like Rione Monti and Aia Piccola—are packed with these quirky structures. Some are still lived in, while others have been transformed into cafés, souvenir shops and pint-sized museums. You"ll even find a church built in trullo style.
