A Monument That Continues to Shape History

Rising above the skyline of Barcelona, La Sagrada Família remains one of the most extraordinary architectural projects ever undertaken. More than 144 years after construction began, Antoni Gaudí's masterpiece continues to captivate millions of visitors while steadily progressing toward completion.

In 2026, the basilica marked a historic milestone with the completion of the Tower of Jesus Christ, coinciding with the centenary of Gaudí's death. Despite this achievement, work on several elements of the basilica remains ongoing, reinforcing its status as one of the world's longest-running construction projects.
