Alberobello
It's an extraordinary place, Alberobello is considered the quaintest town in Italy, it consists almost entirely of trulli (over a thousand of them); a series of urban quarters entirely full filled by neatly whitewashed houses with conical roofs, made of superimposed dry-stone blocks.
In such a fertile country, where some olive trees are more than one hundred years old, all those cones seem to be like breasts, all evocating the ancestral co-operation between mother nature and human labour.
A daily trip here is highly recommended from Trullo della Luna. According to the convention for the protection of the cultural and natural patrimony, Alberobello appears in the list of the world patrimony of UNESCO. The registration in this list (since 1996) hollows the extraordinary value of this place in order to assure its protection for the benefit of the whole humanity.
Many public funds have been spent in order to preserve and study the typologies of the trullo.
Historic evidences demonstrated that Alberobello was governed by the Counts of Conversano since XV century. Only in 1797 the town was set free from Feudal enslavement. For all that period it seems that the Counts obliged by edict people to built only houses of dry-stone blocks.
Thus much is certain: that the origin of the trulli rises back to the feudal period. Some of the feudal world is still persisting: we too had had a direct experience! But this is another story, if you want more info please click here.

Many legends rose about the origins of the trulli, the most charming seems to rise from some ancient edict about taxes, due for the possession of houses. Building a sort of cave as aggregation of drystone blocks seemed the right trick to demonstrate that that was not a true "house" but something like a provisional shelter for people!
