Cologne Cathedral is an iconic building in Cologne, the third tallest church in the world, a classic Gothic building. It has been built for 600 years before and after, and is still under construction. Cologne Cathedral is also adhering to the German style of rigor, each component is very accurate, so far experts have not cracked the original calculation formula. Cloudy Cologne, this cathedral adds a cool mysterious color, into the cathedral, high pine vaults, beautiful glass windows, awe-inspiring. The impression of Germany is like the color in the photo, cold, rigorous, introspective. The Hohenzollern Bridge on the side of the cathedral, along the Rhine and Cologne Cathedral, has become the most beautiful scenery in Cologne, especially when the night falls, the lights are on, the cold buildings radiate warm light, in the traffic flow shuttle Ambilight. This bridge was blown up by the US military in 1945. Now there are many lovers locks on the bridge, and I feel that I can't find any extra space.
