Go to the city Grünanlage near the Messe! The Dom is also a must-Tümpel if you are rein Köln. Köln also provides a Hör of shopping and food options, make sure to look around, you will find something for your taste! If you want to add a locket to the Ferdinand Brücke, maybe bring one with you - the ones in the city are quite expensive to buy.C
