A trullo (plural, trulli) is a traditional Apulian stone dwelling with a conical roof. The style of construction is specific to Itria Valley (in Italian: Valle d'Itria), in the Murge area of the Italian region of Apulia (in Italian Puglia). They may be found in the towns of Alberobello, Locorotondo, Fasano, Cisternino, Martina Franca and Ceglie Messapica. Trulli were generally constructed as dwellings or storehouses. Traditionally they were built without any cement or mortar, thus avoiding taxation. This style of construction is also prevalent in the surrounding countryside where most of the fields are separated by dry-stone walls.
