Incredibly beautiful Park Guel, where you can walk for a long time.
If you like Gaudi's work, you should definitely visit his house.
It is impossible to evaluate the artist's view from photographs, you need to see this beauty with your own eyes.
A great place that has no analogues. He's the only one, and in his own way, the concept. Not everything is perfect there, but the essence of it is individuality. And it's definitely there. I recommend you to visit!
