facade, as well as every detail of the decor, designing furniture and accessories such as lamps, planters, floors or ceilings. This was another point of friction with Segimon, who complained that there was no straight wall to place her Steinway piano. Gaudí's response was blunt: "So play the violin." The result of these disagreements has been the loss of the decorative legacy of Gaudí, as most of the furniture was removed due to climate change and the changes she made to the main floor when Gaudí died. Some remain in private collections, including a curtain made of oak 4 m. long by 1.96 m. high in the Museum of Catalan Modernism; and a chair and desktop of Milà. Gaudí carved oak doors similar to what he had done for the Casa y Bardes, but these were only included on two floors as when Segimon discovered the price, she decided there would be no more at that quality. Architecture Casa Milà is part of the UNESCO World Heritage Site "Works of Antoni Gaudí". It was a predecessor of some buildings with a similar biomorphic appearance: the 1921 Einstein Tower in Potsdam, designed by Erich Mendelsohn Solomon R. Guggenheim Museum in Manhattan, New York, designed by Frank Lloyd Wright Chapelle Notre Dame du Haut, Ronchamp, France, designed by Le Corbusier the Hundertwasserhaus and other works by Austrian architect Friedensreich Hundertwasser Disney Concert Hall in Los Angeles, by Frank Gehry Free exhibitions often are held on the first floor, which also provides some opportunity to see the interior design. There is a charge for entrance to the apartment on the fourth floor and the roof. The other floors are not open to visitors. Constructive similarities Gaudí's La Pedrera was inspired by a mountain, but there is no agreement as to which mountain was the reference model. Joan Bergós thought it was the rocks of Fray Guerau in Prades mountains. Joan Matamala thought that the model could have been St. Miquel del Fai, while the sculptor Vicente Vilarubias believed it was inspired by the cliffs Torrent Pareis in Menorca. Other options include the mountains of Uçhisar in Cappadocia, suggested by Juan Goytisolo, or Mola Gallifa, suggested by Louis Permanyer, based on the fact that Gaudí visited the area in 1885 to escape an outbreak of cholera in Barcelona. Some people say that the interior layout of La Pedrera comes from studies that Gaudí made
