Sister cities

Twinned with Köln

7 of 25 in this atlas

Köln maintains twinning ties with municipalities spanning several continents, including Barcelona, Beijing, Istanbul, Kyoto, Rio de Janeiro, Tunis, and Volgograd. Each of these pairings is confirmed as mutual, meaning both cities formally name the other in return. The connections reach across Europe, Asia, South America, and Africa, reflecting a geographically varied set of formal municipal partnerships rather than a regional clustering pattern.
