The great Catalan architect of the Sagrada Familia recounted in his words, collected by the young students who attended his lessons. The book is enriched with plans, sketches and projects by Antoni GaudÍ, with the addition of an important color photographic insert that shows the magnificence of his masterpieces. Not too many words are needed to remember the figure of the famous architect, theorist and inventor of Catalan modernism, author of unforgettable buildings, green areas and, of course, the masterpiece represented by the Sagrada Familia. Completely absorbed in his project, Gaudí left no theoretical or autobiographical texts, but luckily some of his students meticulously wrote down his thoughts, bestowed by the teacher on those who followed his lessons. In this book, edited by an architect and later the author of numerous books on Gaudí's works, we therefore find the ideas, thoughts and theories of the great architect as if he himself were talking to us, with that immediacy that only dialogue between teachers and learner can guarantee. At the center of the discussion we find not only the famous projects of the master such as Casa Calvet, the Milá, the Park Güell and the Sagrada Familia, but also broader thoughts on architecture, design, the statics of buildings, the relationship with nature and foundations of Mediterranean culture that permeate his masterpieces.
