Antoni Gaudí designed this palace for Eusebi Güell, his most important patron. It was one of the architect's first big undertakings and he expressed all of his original creative genius in it. It was built between 1885 and 1889 and shows early signs of Gaudí's desire to combine the structural and the decorative aspects of architecture. He made artistic use of the iron structural elements and introduced Byzantine domes made out of flattened bricks. Let your visit to the city include a guided tour that starts every half hour.
