In 1882, Antoni Gaudí began construction on the Sagrada Família, a basilica in Barcelona slated for completion in 2026. The National Geographic reports that at the time of Gaudí’s unexpected death, less than 25 percent of the exterior was finished. Even if he had not died prematurely, Gaudí knew he’d never see the completed work; but it didn’t bother him. He believed he was working for God. Whenever asked about the immense time for the project, he answered, “My client is not in a hurry.”
