text: Slide 3 of 21: Started in 1882, the Sagrada Família Basilica in Barcelona was quickly taken over by Antoni Gaudí—described as a “genius or a madman” by architects of the day—with an ambitious design for the church of the future. He would work on it until his death in 1926, but the project would not be completed for at least another century, with construction continuing to this day. A mass of spires and organic forms, it is one of Europe’s most popular tourist attractions, and Gaudí’s work is today recognized as a World Heritage cultural site.
