This whimsical cathedral is renowned as Antoni Gaudí’s principal architectural masterpiece. The design is so intricate that the cathedral was not finished in Gaudí’s lifetime; it has been under construction since 1882 and is scheduled to be finished in 2026, marking the centennial of Gaudí’s death. Don’t miss the incredible stained glass interior. (Photo by Tanatat Pongpibool/Getty Images)
