Casa Batllo is one of the two great buildings designed by Antoni Gaudi, the other being La Pedrera. From the outside, the façade of Casa Batllo looks like it has been made from skulls and bones. The “skulls” are in fact balconies and the “bones” are supporting pillars. Gaudi used colors and shapes found in marine life as an inspiration for his creativity in this building e.g. the colorous chosen for the façade are those found in natural coral. The building was designed by Gaudi as a market home for Josep Batllo, a wealthy aristocrat. This building is a stunning and original work, well worth a visit.
