When I studied abroad in Barcelona in 2010, I visited Park Güell several times. It had nice gardens and walking paths, many examples of the architect Antoni Gaudí’s signature whimsy, a stunning view of the rest of the city stretching out towards the sea below you, and it was free. By the time I took E to Barcelona in 2015 to show him all my favorite places in my favorite city, Park Güell cost 7 euros and had ugly stanchions to keep people out. It’s not an exorbitant fee, and it’s still worth visiting despite the crowds, but it feels a little less magical than it used to.
