How to build modern buildings with dry masonry

Modern buildings are being built by dry masonry. Of particular interest are the Croatian croars and Italian Trullo — small houses built «dry» from stones. Now they are used more often as outbuildings, although they initially served as housing for the peasants. CASONS — small windows without windows, with one room, but TrULLO can be multi -room and have two floors. And everywhere builders adhere to a pyramidal shape.
