Casa Batllo is a building restored by Antoni Gaudí and Josep Maria Jujol, built in the year 1877 and remodelled in the years 1904–1906. The local name for the building is Casa dels ossos (House of Bones), as it has a visceral, skeletal organic quality. It was originally designed for a middle-class family and situated in a prosperous district of Barcelona.
The building looks very remarkable — like everything Gaudí designed, only identifiable as Modernisme or Art Nouveau in the broadest sense.
