An unfinished Cathedral designed by Antoni Gaudi.
We are standing in front of the nativity facade in this picture.
A site to behold!
On the other side of the church is a much starker, darker facade of the Passion of Christ. It was executed by a different artist- who designed the Roman Soldiers to look like this:
The design for the soldiers is taken from another of Gaudi's work (chimneys on an apartment building) but I wonder if George Lucas was inspired by them as well for the design of stormtroopers. A little google-ing will answer this question!
