3. Kaliningrad (Russia in the EU)
Kaliningrad is a striking Russian exclave set apart from the rest of Russia, nestled between Poland and Lithuania on the Baltic Sea. Once known as Königsberg, the city was German until the aftermath of World War II, when it became part of the Soviet Union in 1945. Today, Kaliningrad is a Russian stronghold entirely surrounded by European Union and NATO countries. This unique position ensures it remains a focal point for geopolitical tension and a reminder of the ever-changing nature of European borders.
