Sagrada Familia with fast-track entry and audio guide, Barcelona

Entry with quick access to the Sagrada Família and two downloadable audio guides: one for the temple and one for the rest of Barcelona. Tickets to the temple sell out days in advance, so booking them in advance is what determines whether you can enter or not. Inside are the towers, tall and narrow, and the stained glass windows, which fill the space with color depending on the time of day. The exterior decoration blends nature with Christian themes, carved piece by piece. There's a detail that almost everyone overlooks: at the base of two columns, there's a land tortoise on one and a sea turtle on the other, placed there to represent the land and the sea. The forecast is to complete the temple in 2026, when one hundred years will have passed since Gaudí's death. By then, the work will have lasted 144 years. A note about the reservation: it can be canceled up to before the chosen time slot.
