This venerable and awe inspiring 14th century Basilica is a must see. If you like historic cemeteries, this one is 4 centuries older than the current church. You might want to take the bell tower tour, but the climb is not for those with a fear of heights like me. I did see some pictures from the top and it might be the best view of Barcelona. Being literally grounded, the high point for me was the stained glass. Four of the stained-glass windows are original and were created by one of the finest stained-glass artists of the Catalan baroque period, Josep Ravella. The basilica has the biggest rose window in Catalonia. It is an exact copy of the 14th-century original and was made by Antoni Gaudí's right-hand man, Josep Maria Jujol, after its destruction during the Spanish Civil War. I traveled with the Antifa flag from the Spanish Civil War on my messenger bag, but no one here recognized it. I highly recommend reading Zafon's Shadow of the Wind on your plane ride in, then contemplate it in this church.
