Italian and other dry-stone walls were added Wednesday to UNESCO's list of the world's intangible heritage of humanity. The UN cultural agency announced the news on Twitter Wednesday. UNESCO thanked the countries that presented the bid: as well as Italy, Croatia, Cyprus, France, Greece, Slovenia, Spain and Switzerland.

UNESCO recognised the art of dry-stone walls and the way in which they are built with stones piled onto others without using any other material except dry earth. It is a technique that dates back to prehistoric times and is indicative of the harmonious relationship between humans and the natural world. The committee which oversees the declarations said that the dry-stone nomination is in accordance with criteria of intangible cultural heritage.
