An architect named Antoni Gaudi believed that an architect should be able to envision what something will look like before it is built. He developed a unique modernist style blending Gothic, Art Nouveau and functional elements. Gaudi is most famous for his work on the Sagrada Familia basilica in Barcelona, where he pioneered the use of nature-inspired organic and hyperbolic designs like parabolic arches and twisting columns. Though controversial in his time, Gaudi's idiosyncratic style is now seen as a landmark of Catalan modernism.
