A Curious Blend - M9, 12mm, ~f/6.7, 1/30s, ISO 1600
If you look closely in this image you will see an interesting blend of architecture. On the left you have a typical renaissance cathedral and on the right, arches of a distinct Arab architecture. This is the Cathedral-Mosque of Cordoba and has a fascinating history and story behind it. I won't rehash the full story (you can read the Wikipedia entry) but it is unique in the world in that its the only Catholic cathedral completely encompassed by a Mosque.
