Alberobello in southern Italy’s Puglia region captures the imagination with its distinctive trulli houses. These structures were built using a dry-stone technique passed down over centuries, without mortar or cement, and their unique form comes from layer upon layer of limestone nestled from nearby fields. Alberobello’s trulli are so remarkable that in 1996 the historic center was inscribed as a UNESCO World Heritage Site, where more than 1,600 of these buildings still stand.

Visitors can explore remnants of the original city walls and climb the iconic lighthouse for sweeping views of the Río de la Plata.
