Casa Milà is also called "open quarry". It was the penultimate construction designed by Antoni Gaudi in 1906-1910. Casa Milà was a private residence for businessman Pere Milà and his wife Roser Segimon. The exterior has marine motifs, resembling rocks carved in waves, the forged decoration of balconies is like seaweed, and the play of color and shadows creates the illusion of continuous movement. The interior was designed in a typical architecture style with elliptical and rounded shapes.
