The Palau Baró de Quadras is a small Modernista palace, built between 1904 and 1906 by architect Puig i Cadafalch. The Palau is located on Avinguda Diagonal.The modest size, but the outstanding Palau Baró de Quadras is one of the jewels of Catalan modernism . The building is reminiscent of North-European palaces. The main facade is Gothic in its representation, referring to the Norman Gothic. The long, ornate balcony, with its busts of eminent medieval and Renaissance figures, floral motifs and heraldic shields, and the mansards on the upper floor, are really in keeping with the medieval European style. The gargoyles are particularly impressive. The interior of the palace hall deserves special attention. The wide marble stairs are simply wonderful. The Palau opens to the public every Wednesday between 11 and 13h. Highly recommend.

The museum is not free as some have mentioned, at least not when I was there nor according to their website. The house museum conducts guided tours every Wednesday between 11am and 1pm, which costs €10. The English tour is at 11 and Catalan and Spanish at 12 an 1pm respectively. So quite limited. As for the museum, it a house museum, which was originally a private residence designed by Josep Puig i Cadafalch in the Catalan Modernist architectural style, mixed with Gothic and Neo-Mudejar. The front façade has an impressive façade has impressive Gothic balconies, almost like a bay window covering the enter first floor level of the building. The entrance to the building has demo-roofs typical of Neo-Mudejar buildings has does the upper part of the front. As you enter the building, the elaborate decorations of the stairway, mosaic walls and a glasswork on the skylight makes it instantly recognisable as Catalan Modernism as familiar to anyone who been inside Casa Mila or Casa Batllo. Definitely worth a visit if you can accommodate the limited opening hours.
