Twinned with Helsinki
12 of 15 in this atlas
Helsinki's twinning ties include several other Nordic and Baltic capitals, such as Copenhagen, Oslo, Reykjavík, and Tallinn, all listed as mutual. Links extend further across Europe and Eurasia to Kyiv, Prague, Saint Petersburg, Sofia, and Beijing, also mutual. A smaller group, Berlin, Guadalajara, and Stockholm, appears one-sided, named by Helsinki but not returned in kind.
