Twinned with Copenhagen
8 of 14 in this atlas
Copenhagen names eight municipalities across this atlas as twins, spanning cities from Beijing to Reykjavík and Curitiba to Kyiv. Most pairings, including Oslo, Helsinki, Prague, Beijing, Curitiba, Kyiv, and Reykjavík, are mutual, with each side recognizing the other. Berlin stands apart as one-sided, named by Copenhagen without a matching declaration in return, showing that not every listed link is reciprocated equally.
