Nato has a Russian city. It's called Narva and its main feature is a 12th Century castle overlooking the Narva River. Climb to the top and you can peer down on its ancient nemesis - the fortress of Ivangorod that sprawls along the opposite bank. This spot has long been a place of conflict between east and west. Today, Ivangorod and its fortress are in Russia. Narva and its castle are in Estonia, which means they're in the EU and Nato.
