Occupying Palau Nadal, this museum holds part of one of the world’s most prestigious collections of pre-Colombian art, including gold jewellery, ceramics, statues and textiles. The artefacts from indigenous South American cultures come from the collections of the Swiss businessman Josef Mueller (1887–1977) and his son-in-law Jean-Paul Barbier, who directs the Musée Barbier-Mueller in Geneva. The museum is small but the pieces are outstanding and often rotated, so that the exhibition is never quite the same on return visits. Admission is free on the first Sunday of the month.
