The Cathedral or Dom with its twin spires dominates the skyline. It is the first thing you see as you drive into the city. It’s a must to see from the Riverwalk after dark and even more so to cross the Rhine and view it from the other side. It rivals any Cathedral I've ever seen including Westminster and Notre Dame in sheer beauty and presence.
Plan to visit some of Cologne's other churches.
Four or five are within walking distance of the Dom. You need to learn the legend of St Ursula and also to visit the grave of Albertus Magnus.
Quick Tips:
Two days really isn't enough time to do justice to Cologne. I would advise maybe 4 days. There is a Cologne Pass that you can buy that will get you into museums and on the public transportation as well as giving you a tour of the city.
Cologne has an excellent art museum and also a history museum within the shadow of the Dom. You can see what I mean by the Cathedral dominating the town. It really is everywhere that you look.
Plan to take a guided tour. You can buy tickets at the Tourist office facing the Dom, there is also an American Express Office near by if you need to cash travelers checks. Our tour guide spoke English and German, he alternated. It was a little confusing at times but he was very nice. We crossed the river and got out of the bus on the other side. We had about 10 minutes to take pictures and walk around.
Best Way To Get Around:
You need to take a cab in from the airport but the charge was less than . Our driver was from Iran and assured us that he had no problem with Americans.
This is a great walking city. There is a large pedestrian shopping area with the best prices we found anywhere in Germany and the Riverwalk felt safe to us even at night. We spent as much time walking around as we could. The Rhine is magical at night.
