UNESCO's Alberobello and Matera from Bari
With a private guide, visit two UNESCO World Heritage Sites in one day. First, explore Matera, including the Sassi area, a complex of cave dwellings carved into the mountainside. Nearby, rock churches house 13th-century frescoes. Then it’s on to Alberobello to see the Trulli, an awe-inspiring collection of mortarless limestone dwellings, a prehistoric building technique still used in the region.
