This soaring white structure at the north end of El Raval (just a short distance west of Plaça de Catalunya) has played a key role in the neighborhood’s revival. It brings youth and vibrancy to the area—even the ramps around the building are a key gathering spot for Barcelona skateboard athletes. Designed by American architect Richard Meier, the building applies the lessons of Josep Sert’s building for the Fundació Miró by manipulating angles of exterior walls to allow in natural diffused light. Galleries are often given over to highly conceptual temporary exhibitions, but they do draw on the permanent collection, which is strong in Antoni Tàpies and younger Spanish artists. Guided tours in English are available. The museum is also experimenting with a downloadable app to enable users to access additional audio and video about selected works of art—and to share responses to the work on Facebook and Twitter.
