Ametller House, Barcelona

Built between 1898 and 1900 by the modernist architect Puig i Cadafalch, this structure together with Casa Lleó Morera and Casa Batlló, is a part of the Illa de la Discòrdia (Block of Discord). These three modernist buildings, the deesigns of which clash radically, hold great architectural and aesthetic value. Unfortunately, visitors are not allowed inside, but the view from the street is still impressive. Casa Ametller's design has Central European Gothic influences, which is particularly evident in the pyramid-shaped roof; a touch of Catalan Gothic style is visible in the window arches, but on the whole, it's clearly a modernist design.
