The Puerta de Alcalá, the Prado Museum and the monastery of El Escorial are some of the monuments built with berroqueña stone, the traditional name of the high-quality Madrid granites which are also used in airports, for example Athens, and modern shopping centres around the world such as China. As with renowned wines and cheeses Spanish geologists now propose to the International Union of Geological Sciences that these granites should become part of the list of natural stones with designation of origin because of their cultural and economic importance.
