Trullo
Trullo (in plural trulli) is a traditional building with a conical roof. It is typical for the Itria Valley (Valle d'Itria) in the southeastern Italian region of Apulia (Puglia). Trullo was used for dwelling and storing. They were built without cement or mortar. This fact enabled the builder to avoid payment of taxes. Trulli were typical for the landscape with numerous fields separated by dry-stone walls. In the town of Alberobello on top of trullo people put a pinnacle. Such a pinnacle vary in its appearance and often has some symbolic meaning. Very often people painted different symbols on the conical roof itself. These symbols are planets, the evil eye (“malocchio”), a cross, a heart, a star and crescent etc.

Walls of trullo are very thick. In summer people won't feel the heat and in winter the walls will serve as an inslulator from the cold weather. In almost all cases every trullo is actually only one room. So, you can often see several trulli connected together. Nowadays many trulli are arranged for tourists. Trulli are part of the UNESCO world heritage programme. It is interesting to mention that some trulli exist in the Rheinhessen (Rhine-Hesse) wine region located in the German state of Rhineland-Palatinate. They served as huts for the vineyard workers in the 18th century.
