Even if you are not a contemporary art fan, a visit to Es Baluard will be a highlight of your visit to Palma. The venue is just stupendous - a really eye-popping use of the old fortress of Sant Pere & part of the Renaissance city walls, completed only in 2004. The views of the city from the rooftop broadwalk alone justify the entrance price (6 Euros - concessions 4.50 Euros). You can actually access part of the roofline free from two or three outside points - though the ramps and staircases are somewhat confusing and seem to end in blank walls. The cafe and some outdoor sculpture is also accessible free.
Inside works by Miro, Tapies, Matisse, Dali, Gauguin & a variety of 19th to 21st century artists hang in dramatic galleries and hanging spaces in both permanent and temporary exhibitions. There is a selection of Picasso ceramics in one small space which I found rather disappointing - though that was the one downside of the whole visit.
If you bring kids - get them to search for the rats on the roof (sculptures!). Most areas are easily accessible to people with disabilities. English-speaking staff are on hand to help and even explain what the artworks are about.
