One of Puig i Cadafalch’s most striking flights of Modernista fantasy, Casa Amatller combines Gothic window frames with a stepped gable borrowed from Dutch urban architecture. But the busts and reliefs of dragons, knights and other characters dripping off the main facade are pure caprice.
The pillared foyer and staircase lit by stained glass are like the inside of some romantic castle. The building was renovated in 1900 for the chocolate baron and philanthropist Antoni Amatller (1851–1910).
The 1st (main) floor has been converted into a museum, with period pieces and original furniture and decor, which you can visit by guided tour. Amatller was a keen traveller and photographer (his absorbing shots of turn-of-the-20th-century Morocco are occasionally on show).
There is a one-hour guided visit in English at 11am; 40-minute express tours run throughout the day and include a multimedia tablet. You can also take a 40-minute multimedia tour that includes a taste of Amatller chocolate in the original kitchen. It's free to wander into the foyer and admire the staircase and lift.
