Today we came to this place again, just like in 2019, exactly on the Monday after the town festival. A note on the door of the basilica informs that it is closed during the entire festival from 1-9 September. Very unfortunate!

Completely destroyed by the German Condor Legion in the Spanish Civil War. https://de.wikipedia.org/wiki/Luftkampf_auf_Guernica A well-worth seeing exhibition in the central square shows the horrors of the civil war. The Spanish spelling with "ue" probably goes back to Picasso.
