I already know Gaudi’s phantasmagoria: the commissioned houses that curve like ocean waves or flash in the sun as though they were covered in fish scales, the Art Deco-Gothic cathedral spires that replicate eternity via never-ending construction, the public park that simulates an underwater landscape. I already know the urban legend that Walt Disney, after spending time here as a young man, would forever replicate the fanciful stone gargoyles, arches and spires of the Barri Gotic in his cartoon worlds, and in the Fantasyland of his first theme park in California.
