Restored and remodeled by the Spanish modernist architect Antoni Gaudi in the years 1905–1907, Casa Batllo is now one the most overlooked buildings by the tourists who visit Barcelona. Although Casa Batllo is a museum now, Gaudi designed it for for a wealthy Barcelona Aristocrat.
The local name for the building is Casa dels ossos (House of Bones), and indeed it does have a visceral, skeletal organic quality.
Casa Batllo’s roof has been compared to a reptilian creature, the backbone of a gigantic dinosaur, the dragon killed by St. George (Sant Jordi being the patron saint of Catalan).
