In light of the growing and general recognition of Gaudi's work, 150 years after his birth, I ponder is the reason for this phenomenon, which is so unusual in the field of architecture. Gaudi did not become a success as a result of the quantity of works completed, since he only directed about 20 important projects. Nor is his success due to the wide geographic diffusion of his buildings, since the majority of them are concentrated in the city of Barcelona. Neither is the architect's fame due to the fact that he was a great promoter of his work and character, since he isolated himself from everything that could disturb his work. Nor were his proposals accepted with enthusiasm by his contemporaries who, in general, were hostile towards them. Therefore, we see that it is not easy to find reasonable answers that justify Gaudi's current notoriety, nor the indifference that he was subjected to, including just before his death in 1926.
