City Walls 
Description
The walls of Cologne were once enclosed the old town, with 12 towers and around 7Km of walls protecting the heart of the city. As the city expanded the walls were pulled down and very little survive today, though the parts that do are kept in good repair, in particular the 5 remaining towers, which have all found alternative uses, mostly as homes for the different carnival groups. You can easily follow the line of the walls as the ring road follows closely, more conveniently the 12 and 15 tram lines run along the same route and provide a quick and easy way of moving between the different sites.
