Apulia
Apulia Stay: The iconic architecture of Apulia—the “heel” of Italy’s boot—is the prehistoric trullo, a cylindrical whitewashed house with a cone-shaped roof of stacked gray stones. There’s no greater concentration of trulli than in the UNESCO-protected town of Alberobello, where whole neighborhoods are made of the structures—and the local entrepreneur behind Trullidea has fixed up dozens of the abandoned ones and rents them to visitors.
