Alberobello!

The trulli are ancient buildings conical stone "dry" of prehistoric origin, present throughout the Itria Valley, but in spite of the development areas of the trulli are found archaeological remains of prehistoric times, and foundations of stone huts dating the Bronze Age, there are no particularly ancient trulli: this is justified by the fact that rather than to repair the same in the event of insolvency, which is preferred for economic reasons demolished and rebuilt, reusing the material.
The trullo was a typical peasant, where Butted, the one who cultivated the land of the owner, could have a bed to sleep and keep the tools of the field. Children would sleep in alcoves carved out niches as directly into the wall and divided from the main through curtains. Some wooden beams, still visible today in the trulli, had no structural function but rather serve to hang the food and supplies, keeping them off the ground (often the floor, in clay, was shared by people and pets).
It is believed that once the Trulli were used to evade payment of taxes on homes. There are various theories about it. One of them states that the Trulli were used to communicate through smoke signals the arrival of any control, in that case were literally roofless, waiting to be rebuilt once the danger passed. One popular rumor has it that as we approach the coming of the owner who applied for payment of duty for residence in the soil, cozzari enough to pull off a single stone to bring down the whole building, making it all appear as a simple pile of stones.
