Also known as La Seu, this was an amazing Gothic style Cathedral with beautiful stained glass. The inside was even better than the outside. Some Gaudí styles were adopted here, but not all (and some of his ideas were a bit weird, so I'm not surprised). Two cool things I learned from our tour guide: the main rose window contains a "hidden" Star of David, and twice a year (sometime in Feb and Nov) at around 8am in the morning, light through the main (western) rose window projects an image of the rose window onto the back wall underneath the smaller eastern rose window, together creating a perfect figure 8 (or infinity), representing a perfect union. We didn't get to see this, but if scheduling permits, visiting on those days would be an amazing treat!
Definitely worth the admission fee to see this place, though it would be best to come with a tour guide (or have an audio guide) to really understand and appreciate the history of the cathedral.
