I recently visited two really amazing and beautiful cities "Barcelona and Florence". We planned to visit these places because when last time we visited Europe these were the cities which left behind and we weren't able to cover them. But this time we planned The trip accordingly, so these were the places which we visited. The reason behind this decision was that Barcelona is my favorite city because I follow FC Barcelona since my childhood, and the city also has the famous Sagrada Familia, and other Gaudi's masterpieces, so I was really excited to visit Barcelona. And we chose Florence because This was the only major city in Italy which was left uncovered. And the famous Duomo Florence was another reason. Barcelona was a great experience as the city has such great architecture and layout that no one can't hate it. And Sagrada Familia is a great example of a true Catalan masterpiece, it was designed by famous Catalan architect Antoni Gaudi who has contributed to many Famous attractions of Barcelona such as Casa Batllo, Casa Mila, Park Guell, etc. These are the most visited places in Barcelona and If you are visiting Sagrada Familia then don't forget to book Sagrada Familia tickets in advance. On the other hand, Florence is also not far behind in terms of tourist attraction as Florence has two one of the most visited tourist places like the great Duomo Florence, the Uffizi Gallery, etc. These places host millions of tourists every year hence, you Should always book Duomo Florence tickets in advance so that you don't face problems while entering the Dome. The Duomo is the largest brick made dome in Europe and one of the largest in the world. You can also skip to the top of Duomo Florence and have an aerial view of the whole city.
