Old City
Cologne's Old Town, on the left bank of the Rhine, is considered the city's birthplace: Even before the year 50, when Cologne was elevated to Colonia Claudia Ara Agrippinensium, there was a settlement here, and the Roman harbour was located around Groß St. Martin. It is bordered by the Rhine and the semi-circular Ringe, while the axis formed by Hahnenstraße, Neumarkt, and Cäcilienstraße separates Altstadt-Nord and Altstadt-Süd.Here you'll find Alter Markt and Heumarkt, the City Hall, and the alleys of the Martinsviertel with their breweries, as well as museums and Romanesque churches. The Hauptbahnhof, the city's most important railway hub, is itself located in Altstadt-Nord; from there you can walk.
