Located in the Itria Valley and UNESCO Heritage Site, the historical limestone constructions, known as trulli, represent a milestone in the Apulian architecture.

The trulli of Alberobello are an exceptional example of a building technique that has survived from prehistoric times until to date.
The site consists of the Monti and Aja Piccola quarters of Alberobello, and some individual buildings elsewhere in the town.
Trulli are built without using mortar: the stones are laid on top of each other. They are also characterized by their dome-shaped roofs. These roofs are in some cases painted with a magical or pagan symbol.
There are many stories about the origins of this construction style. In the Middle East, burial tombs were already built in the same manner thousands of years ago.
Also it is said that this way of building makes it easier to quickly dissemble the house and relocate, or that in this manner taxes could be evaded.
