Antoni Gaudi may not have been born in Barcelona, but he has left an indelible mark on the city. His works were underscored by genius, attention to detail and innovation. They were inspired by a deep love of nature, and a deeply held Roman Catholic faith. Gaudi's soaring or quirky buildings impress on the macro and minor scales, are both technical and and spiritual triumphs. None more so than the great cathedral of our age, the Sagrada Familia, whose construction contines 100 years after it's creator's death.
