Alberobello’s skyline is made not of towers but of pale stone cones. Across this town in Puglia’s Itria Valley, the trulli—traditional limestone buildings with corbelled roofs—turn ordinary streets into a distinctive historic landscape. Their appeal is visual, but the story is also practical: these structures were shaped by local stone, rural livelihoods and building knowledge passed through generations. The most rewarding visit looks beyond the picturesque roofline to understand how the houses work, which districts are protected and how a living town can welcome visitors without becoming a display set.
UNESCO describes the trulli as remarkable examples of corbelled dry-stone construction, a technique that uses carefully placed stone without mortar or cement. Their earliest examples date from around the mid-fourteenth century. A typical building has thick, double-skin walls, a roughly rectangular room and a conical, domed or pyramidal roof assembled from limestone slabs. The stone came from local ground and nearby fields; excavation for the structure could also create a cistern beneath the floor, linking construction with water storage in a landscape where rain mattered.
