[EN] Tile vaulting is an ingenious, fast, lightweight, and inexpensive technique which appeared in the Middle Ages. Unlike other construction techniques and procedures, it was not abandoned with the advent of the Modern Age. Indeed, the scarcity of timber which had led to its invention worsened in Europe, further highlighting its great versatility and convenience. The cheaper widespread distribution of materials such as natural cement, Portland cement, and iron resulting from the Industrial Revolution meant that tile vaulting took bold steps to incorporate these materials, thus ensuring the survival of the technique throughout the 19th century thanks to architects such as Rafael Guastavino, first in Spain and later in the United States, and the entire generation of Catalan Art Nouveau architects. This centuries-old construction technique remained in use throughout 20th century Modernism, due to both its formal expressiveness and its affordability, especially in times of scarce resources.
