Alberobello is known as the Capital of the Trulli. The trullo is a fascinating architectural feature of this area of Puglia. The trulli are old, round buildings of limestone blocks built without mortar. The conical roofs are made up of flat stones ('chianche').

Alberobello has special status internationally - designated a UNESCO world heritage site - because its collection of some 1,500 trulli in an urban environment is unique.

Some of the trulli are now used for stores, restaurants, and lodging. But many are still inhabited by locals, who are very friendly to visitors.

It`s a world heritage site and a tourist attraction. The town is also the centre of an annual pilgrimage to the Basilica dedicated to the martyr saints Cosma and Damiano.
