Begun in 1248, the construction of this Gothic masterpiece took place in several stages and was not completed until 1880. Over seven centuries, successive builders were inspired by the same faith and a spirit of absolute fidelity to the original plans. Apart from its exceptional intrinsic value and the artistic masterpieces it contains, Cologne Cathedral testifies to the enduring strength of European Christianity.

My trip to Cologne was an extension of a trip I did to Eindhoven in the Netherland, where I visited a friend there. She told me that we could do a short drive (about an hour and half) from her place to Cologne. As a mad traveller, I am always excited of the prospect of seeing another country, another place, I immediately got excited and agreed to do a day trip there.
We set of around mid morning on the Sunday, spend a few hours venturing the city and had lunch before heading back to Eindhoven that afternoon. I think I need to visit Cologne again one day, to really explore the city well, perhaps by bike.
