One of my favorite things to visit in Barcelona is the world-famous Sagrada Familia. You could spend a whole day in the church and still not see all the beautiful details it has to offer. I especially love the colorful chandelier hanging over the altar. The bright lanterns aren't something you would normally expect to find in a church, but then again this isn't just any church. La Sagrada Familia is a true architectural and cultural masterpiece that's not to be missed on any trip to Barcelona.
