The foundation of the castle on the island of Pantelleria can possibly traced back to the Arab or Byzantine period in Sicily, even if it is not attested with certainty before the 13th century.
The Castello Barbacane is located in the centre of Pantelleria town at the entrance of the old harbour and is accessed via a staircase from the Via Castello. It was a bulwark to protect the maritime trade of the island, facing the harbour on one side and walls lapped by the sea on the other side. Until just over a century ago, the castle was the predominant element of the walled city
The castle is well preserved and worth a visit.References:
The trulli, typical limestone dwellings of Alberobello in the southern Italian region of Puglia, are remarkable examples of corbelled dry-stone construction, a prehistoric building technique still in use in this region. These structures, dating from as early as the mid-14th century, characteristically feature pyramidal, domed, or conical roofs built up of corbelled limestone slabs. Although rural trulli can be found all along the Itria Valley, their highest concentration and best preserved examples of this architectural form are in the town of Alberobello, where there are over 1500 structures in the quarters of Rione Monti and Aja Piccola.
The property comprises six land parcels extending over an area of 11 hectares. The land parcels comprise two districts of the city (quarters or Rione Monti with 1,030 trulli; Rione Aia Piccola with 590 trulli) and four specific locations.
Trulli (singular, trullo) are traditional dry stone huts with a corbelled roof.
