Alberobello is a fascinating place to visit, above all because of the trulli, the traditional dome shaped buildings made from the local stone. Trulli is a word that derives from the Greek "tholos" (trans: "dome"), the typical shape of the buildings. Each whitewashed “trullo” is built without an lime or cement, and has a conical roof on the outside, which is dome shaped inside, and consists of a square central compartment that communicates through arcades with the kitchen and other rooms. The Trulli were strategically built to throw off the government to hide under the law and evade taxes, so they were meant to look like an “uninhabited settlement”. For this reason, the Trulli were built without mortar so they could easily be disassembled quickly if needed. You will see trulli throughout the countryside of the region but there are more in Alberobello than anywhere else (more than 1000) and because of this the town is now a listed UNESCO World Heritage Site.
