Rotating exhibitions of portions of this private collection of mostly 20th-century art (some 1200 works in total) offer anything from Man Ray’s photography to sculptures by Alberto Giacometti. Over two floors, you are most likely to run into Spanish artists, anyone from Picasso to Jaume Plensa, along with a sprinkling of international artists.

It makes a refreshing pause between the crush of crowded Modernista monuments on this boulevard. Indeed, you get an interesting side view of one of them, La Pedrera, from out the back.
