Here is a small collection of Modernist buildings in the centre of Barcelona. They are, all, very close to the main touristic attractions such as Casa Battló or La Pedrera. I warmly recommend you add them to your map if you’re interesting in seeing just how playful and diverse the architecture of the beginning of the 20th century has been.
Circulo equestre. 1911 winner of the Barcelona council award for the best building of the year
Casa Codina. Medieval inspiration and modernist floral decoration
Casa Sayrach. Or casa de la nata
Fundació Antoni Tàpies. Marking the transition to the new Modernista (Catalan Art Nouveau) style
