Casa Mila ("La Pedrera") (1906 - 1910) This was Gaudi's last work before he devoted himself entirely to La Sagrada Familia. When it was built, Casa Mila was ridiculed and strongly attacked for its departure from established construction principles.

Gaudi built the corner apartment building around two circular courtyards. The intricate ironwork balconies by Josep Maria Jojol twist against the wave-like walls of white stone. There are no straight walls anywhere in the building. The multitude of sculpted air ducts and chimmneys on the roof look like strange creatures from another planet.
