Modernista architecture was not only the product of the convictions of innumerable architects, it also received the unconditional support of property owners. A series of favorable social conditions, but above all this meeting of passions, led to the emergence of Barcelona's Eixample, a unique urban project. In the pages of this book we discover an array of astonishing works by following an itinerary designed to be both instructive and pleasurable. A stimulating promenade, with none of the characteristics of a simple catalog, on which the reader will be able to discover, admire and savor the best of Modernisme.
