The Sagrada Familia is the magnum opus of the famous Catalan architect Antoni Gaudí. The cathedral was the finale to his incredible Modernist career, and it has been under continuous construction since 1882. Over time, the so-called 'architect of God' dropped all his other work so that he could focus exclusively on this project, which he did until his untimely death in 1926. The Sagrada Familia is due to be finished in 2026, on the 100th anniversary of Gaudí's death. By that time, the construction of the Sagrada Familia will have taken 144 years.
