Will he be canonized? Antoni Gaudí, whose centenary is in 2026, is well known now and much loved and revered. In this lecture, his work will be explored in detail. It will be shown how he engaged with nature in the most innovative and extraordinary ways. Inspired by honeycombs and spiders' webs, armadillo skins and mushrooms, trees and whales' bellies, he worked with extraordinary ceramicists, iron workers, tilers and decorative artists. We will look at his public and private buildings and his relationship with a wealthy and demanding patron. Private shy and retiring he was also humorous and witty in his extravagant style. However, it will also be the aim of this lecture to uncover some of the other architects working in Barcelona over the turn of the twentieth century; Domenech y Muntaner and Puig y Cadafalch. Attention will be paid to several significant and ravishing buildings and some less well-known buildings in Barcelona.
