Berlin Dom
In all of Europe, or even the world in my humble opinion, the Berliner Dom is the most spectacular cathedral I have ever been inside of. It dates back to somewhere around the fourteen hundreds and was built, I believe, by the Prussians. The tower in the background is a TV tower, built by the Russians in an attempt to demonstrate to the western world its technological superiority. It was built during the Russian occupation of East Germany. The views from the top are spectacular.
