This building by Puig i Cadafalch (1900) is part of the famous "Apple of Discord". It has a beautiful façade with frescoes bearing floral motifs and large Gothic windows. Note, in particular, the exquisite finesse of the balconies and doorways. The building houses the Amattler Institute, with its small collection of glasswork, paintings and sculptures from various periods, as well as a library and a sound archives room specialising in art from the 10C to the 20C.
