Barcelona
In Barcelona it's all about Gaudi, Gaudi, Gaudi.  Here I am at two of his famous residential buildings, the Casa Battlo (left) and the Casa Mila (La Pedrera).
I also visited his famous cathedral, La Sagrada Familia.  As you can see, it's not yet completed, even though Gaudi's been dead since 1926.
When I got tired of Gaudi, I went to the Maritime Museum.  Check out this old submarine!
