This Gothic Monastery houses collections from Barcelona's City History Museum, but if you've only got an hour a so, skip the exhibits in favor of a walk around. Founded by King James II of Aragon in 1326, the Monastery or Monestir in Catalan is a welcome oasis after time spent in Barcelona's hectic city center. Three floors of cloisters frame a beautiful garden crowded with orange trees and palms. In their shade, watch goldfish swim through the green waters of the garden's central fountain. If you've got a little bit more time, don't miss the 14th century stained glass windows in the chancel.
Opening hours are 10am to 2pm Tuesday through Saturday October through March, and they are extended to 5pm April through September. Sundays, the Monastery is open until 8pm, and admission is free after 3pm. Get there via FGC, L6. Stop: Reina Elisenda
