Gaudí was incredibly ahead of his time with the design of the cathedral. Even as a non-believer I highly recommend that people visit this building at least once in their lifetime. It's unbelievable in person and I actually got vertigo looking up into it. It's a truly awe inspiring building and it's shocking that it was designed in the 19th century.
