Although we've lived in Spain for 14 months, we haven't been able to visit Barcelona, unfortunately. I feel sad that we didn't especially after this post, because the pictures are breathtaking. All these structures and materials blew me away. I knew that the Sagrada Familia is one to visit, but I've never seen beautiful detailed pictures like this before. Amazing! The tower does indeed look futuristic! Thank you for sharing this great post, I really enjoyed every bit of it.
