Alberobello is a small town and comune of the Metropolitan City of Bari, Apulia, southern Italy. It is famous for its unique trullo buildings. The trulli of Alberobello have been designated as a UNESCO World Heritage Site since 1996. Alberobello is one of I Borghi più belli d’Italia (“The most beautiful villages of Italy”).Alberobello is the only inhabited centre with an entire district of trulli, and is considered to be the cultural capital of the trulli of the Itria Valley.
The history of the trulli is linked to the Prammatica De Baronibus, an edict of the 15th-century Kingdom of Naples that subjected every new settlement to a tribute. In 1481 the Counts of Conversano D’Acquaviva D’Aragona from 1481, owners of the territory of Alberobello, then imposed on the residents that they built their dwellings dry, without using mortars, so that they could be configured as precarious buildings and easily demolished.
Having to use only stones, the peasants found in the round form with self-supporting domed roof the simplest configuration. The roofs were embellished with decorative pinnacles representing the signature of the architect (master trullaro).
