Amazing architecture you must see at least once in your life

It was my first time in Europe, and I came to Barcelona, ​​Spain. After a stroll around the old town, I took the subway to Sagrada Familia. If you turn around as soon as you leave the station, you will be greeted by a magnificent structure. You purchase tickets online in advance to enter, but I recommend getting one early as they sell out quickly. This time I booked for the 3:15pm slot, which was the time when the sunlight was shining through the stained glass, coloring the inside of the cathedral in orange and blue, creating a fantastical sight.
