Avinguda Diagonal, 373
Houses and emblematic buildings
The Palau Baró de Quadras is a modernista mansion designed by Josep Puig i Cadafalch in the late 19th century. On Avinguda Diagonal, it features an exuberant neo-Plateresque façade by Eusebi Arnau, full of intricate, eye-catching detail. On Carrer Rosselló, by contrast, the style becomes more restrained and abstract. Inside, the grand staircase, mosaics, sgraffito and wrought iron create a sequence of carefully composed spaces. Two façades, two styles and a shared ambition: to show just how far Barcelona’s Modernisme could go.
