This masterful work by Gaudí is part of the famous "Apple of Discord" and was built between 1904 and 1906 in pure Modernist style, with ceramic coloured glass disks and a fishscale roof. At the time, the unique enlarged windows on the first floor gave rise to the nickname "House of the Yawns". While the exterior is overpowering in its dynamism and profusion of images and colours, the inside continues in the same theme, creating an aesthetic coherence and unparalleled beauty throughout.
