Casa Batlló is a building restored by Antoni Gaudí and Josep Maria Jujol, built in the year 1877 and remodelled in the years 1905–1907. The local name for the building is Casa dels ossos (House of Bones), and indeed it does have 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. The ground floor, in particular, is rather astonishing with tracery, irregular oval windows and flowing sculpted stone work
The buildings flanking the entrance, though very original and remarkable with fantastically shaped roofs with unusual pinnacles, fit in well with the use of the park as pleasure gardens and seem relatively inconspicuous in the landscape when one considers the flamboyance of other buildings designed by Gaudí.
It’s a strange, enchanting place where his passion for natural forms really took flight to the point where the artificial almost seems more natural than the natural.
