Dedicated to Antoni Tàpies (1923–2012), Catalunya’s leading late 20th-century artist, this museum tends to emphasize late works and large-scale pieces (the collection is largely based on gifts from the artist and his wife). Changing exhibitions show Tàpies’s evolving viewpoints and underscore his role in bringing unconventional materials (gravel, broken sticks, chunks of cement) into high art. Seeing so many works by Tàpies in one place illuminates how, like many Spanish artists, he returned repeatedly to the motif of the cross for works both secular and (in his own abstract way) sacred. Since it’s in L’Eixample, it’s no surprise that the museum occupies a Modernista landmark: the former home of publishing company Editorial Montaner i Simon, built by Lluís Domènech i Montaner from 1880 to 1882 (the company belonged to his mother’s family). The pioneering structure has a jaunty Moorish cast to it. Tip: Make sure to check the schedule online, because the whole museum closes between exhibitions.
