Enter Antoni Gaudí’s UNESCO-listed masterpiece, the tallest church in the world. Wander through its forest-inspired nave, where branching columns reach toward intricate geometric ceilings, while vibrant stained-glass windows fill the basilica with shades of blue, green, gold, and orange. Your timed-entry ticket provides access to the basilica’s interior, the apse and main altar, and the Sagrada Família Museum, featuring Gaudí’s original models. Before or after entering, take time to admire the remarkable Nativity and Passion façades from up close.
