Barcelona is home to numerous architectural gems created by the Modernist innovator, Antoni Gaudí, and few are more spectacular than the Sagrada Familia–one of the world's most visited buildings.

Get fast track entry with pre-arranged admission and enter the astonishing interior of this majestic Roman Catholic church, where a vibrant clash of Gothic and Art Nouveau designs burst across the walls. Each of the 5 aisles in the Latin cross floor-plan are richly adorned with symbolic details, and you can see them all with your skip-the-line ticket.

Visit the Sagrada Familia Museum to learn more about the life and career of Antoni Gaudí. Study drawings, plaster models, and pictures illustrating the history and development of the basilica from its inception to the present day. The project was so ambitious that less than a quarter had been built by Gaudí's death, and indeed construction is not due to be finished until the centenary of that date, in 2026!
