(& Itria Valley)

       
      It raises in the middle of Itria Valley (Trulli's Valley) and it is the most important expression of the Apulia rural landscape. Alberobello is famous around the world for having these particular buildings: it was declared as national monument and then as world heritage by the UNESCO. Trulli, limestone dwellings found in the southern region of Apulia, are remarkable examples of drywall (mortarless) construction, a prehistoric building technique still in use in this region. 

      The trulli are made of roughly worked limestone boulders collected from neighbouring fields. Characteristically, they feature pyramidal, domed or conical roofs built up of corbelled limestone slabs. 
There are some important place to visit in Alberobello: Trullo Sovrano, belonging to the 17th century, which is 15 metres high; S. Antonio Church, a religious building in the shape of a trullo and Trulli Siamesi (twin Trulli).

      Near to Alberobello, other interesting towns are: LOCOROTONDO, with its characteristic circular historical centre, located on a hill, CISTERNINO and its old districts that remind to the past, CONVERSANO, old and noble town whose princes left many signs of their power and good taste and CASTELLANA, the town of the characteristique caves, in which there are many stalactitic and stalagmitic formes.
