The Trulli (from the late Greek τρουλλος, cupola) is ancient constructions in stone “to dry”, conic sections, of protostoriche origins; however, although in the zones of development of the trulli they are recovered reperti archaeological of preistorica age, or foundations of going back huts in stone to the age of the bronze, do not exist trulli particularly antichi: this would be justified from the fact second which rather than to supply to the repair of the same one in dissesto case, it was preferred to pull down it and to reconstruct it for economic reasons, ring-use of the material. Trulli the more antichi than which us rests trace nowadays have been constructed in XVI the century to ridosso of the pugliese cape of the Murgia. The Trulli has been declares patrimonies to you of the humanity from the Unesco. The trulli, of circular plant, modeled collections are constructed with stones and so as to to create one risen of tile; they can be composed from a simple space, or from more atmospheres, than generally they come added for gemmazione around the space centers them. They are habitable only to the flat land [1], but under they they can be obtained of the reserviors in order to conserve the piovana water. The thick walls of the trullo were constructed to dry with a particular technique of stone superimposition and a lot often was equips you of an interstice, where it came placed of the terriccio, in order to maintain to the freschi inner atmospheres of summer and warmth of winter. These come sormontati from one pseudo-cupola (ovverosia one series of horizontal slabs disposed to steps re-entering towards the high), constituted from a double limestone stone layer: an inside, of thick slabs piu', said chianche, and the other outside, constituted true and just the roof, in thinner slabs, said chiancarelle.
