Build my Cologne planAbout Cologne
City overview
Cologne sits on both banks of the Rhine, with the Dom, Altstadt, Belgian Quarter, Ehrenfeld, Suedstadt, Deutz, and the rings tying Roman history, medieval churches, breweries, museums, carnival, and river bridges into one compact city. The cathedral dominates the arrival from Hauptbahnhof, but the local identity comes just as much from Koelsch beer halls, neighborhood squares, and Karneval season.
Food & drink
Cologne food centers on Koelsch beer, Himmel un Aad, Halve Hahn rye rolls with Gouda, Reibekuchen, Sauerbraten, blood sausage, and brewery snacks served by fast-moving Koebes waiters. Brauhaus Frueh, Paeffgen, Sion, Malzmuehle, Alter Markt, Zuelpicher Strasse, and Ehrenfeld are the first food-and-beer map.
