Interior detail from the Casa Batllo, Barcelona, designed by Antoni Gaudi. A remodel of a previously built house, it was redesigned in 1904 by Gaudi and has been refurbished several times after that. Gaudi's assistants Domenec Sugranes i Gras, Josep Canaleta and Joan Rubio also contributed to the renovation project. The local name for the building is Casa dels ossos (House of Bones), as it has a visceral, skeletal organic quality.
