The art of dry stone walling becomes UNESCO heritage
On 28 November 2018 Italy and Puglia with its countless dry stone walls have won a prestigious worldwide recognition. Unesco in fact, has entered, "THE ART OF DRY WALLS" in the list of intangible elements declared heritage of humanity. This "art" represents one of the first examples of human manufacturing both for residential purposes like the Trulli and for purposes related to agriculture and in particular to the terracing necessary for crops in the steep area. This particular technique, present in the south of Italy, concerns stone building by massing stones on top of each other without the use of glues and in perfect harmony with the environment. Examples of dry stone walls are present in the Valle d'Itria, an area that includes the city of Ostuni, Locorotondo, Martina Franca and Alberobello.
