I took this in Barcelona inside the Sagrada Familia. The light shining through the stained glass was nothing sort of amazing. Even though the cathedral was plenty crowded you could easily get lost in contemplation as though you were all alone.
In the morning I was at the other main cathedral in the Gothic quarter, but this Antoni Gaudi masterpiece transcends traditional concepts and takes architecture and design to a new level that is quite frankly beyond belief. Regardless of religious persuasion, this is worth seeing.
