I have high on my list Barcelona just because of all these treasures that are resting on there. The architecture is no doubt unique and way different than anything else.
I always loved to discover other places just to see what they have in plus than others and how they get remarked by tourists and yeah, Barcelona is high on this list.
Your post is structured amazing and all the info is perfect for who is planning to visit Barcelona soon and more than that it helped me add a few more destinations on my bucket list because there are a few I didn't even know about.
Thanks for this and stay safe in your future travels! :)
