The ceiling of La Sagrada Familia in Barcelona. The building is impressive from the outside as well as from the inside. After the visit there, I was left speechless. It's amazig how Gaudi designed all, even the smallest details to symbolize elements of Christian faith.
The inside was designed to symbolize trees and three branches. I just loved it! It seems like the buildig ia alive and the more you look at it, the more you see and understand.
