Written by leading experts in medieval architecture, Talleres de Arquitectura en la Edad Media addresses one of the driving forces of economic development in the Middle Ages: the building industry (abbeys, cathedrals and some civil buildings) that developed from the 11th to the late 14th century. On the basis of specific cases including St Mark’s basilica, the cathedral at Santiago de Compostela, the Duomo in Milan, Montecassino and many more, the authors analyse the role of the main artist (architect, sculptor, stonecutter, etc), the master-apprentice relationship and the different construction phases, delving into their tiniest, hidden particularities, the traditions and secrets of the workplaces, work tools and also the tightly woven network of financial and social relationships linking patrons, artists and citizens in what were veritable group ventures.
