Kaliningrad is the westernmost region of Russia. It is located on the Baltic Sea, stuck between Poland and Lithuania, in fact, it does not share a land border with mainland Russia.
The largest city in the region, also named Kaliningrad, was formerly known as Königsberg until 1945 when it was annexed to the Soviet Union.
During the Cold War era, Kaliningrad had a strategic military importance - traces of this period of history can be found all across the city and region.
Despite its small size and isolation from the mainland, the region feels as Russian as any other parts of Russia.
