Antoni Gaudi (1852 - 1936) left his modernist mark on barcelona in an unmistakable way. From Casa Batllo with it's underwater sea themes and sinuous lines, to La Pedrera's wavy, cliff-like facade and dream-like chimneys, to the curving mosaic bench of Park Guell, to his unfinished masterpiece, the church of the holy family (La Sagrada Familia - construction completion estimate, 2020), Gaudi's genius is writ large in the face of barcelona.
