This cathedral in Barcelona, Spain was designed by Antoni Gaudi. Aside from the cathedral, I’ve also seen his other work around Barcelona, such as his house and Park Güell. This cathedral was massive. I remember trying to take a picture with it, but my parents could not fit the entire cathedral in the picture. The fine detail was what made this cathedral one of the most impressive structures I’ve ever seen. When I visited, there was an enormous amount of construction going on, which limited the inside visiting capacity. However, I hope to be able to see the inside of it someday.
