Kaliningrad

Kaliningrad, until 1946 known as Königsberg, is the largest city and the administrative centre of Kaliningrad Oblast, the westernmost oblast of Russia. The city is situated on the Pregolya River, at the head of the Vistula Lagoon on the Baltic Sea, with a population of 489,359 residents, up to 800,000 residents in the urban agglomeration. Kaliningrad is the second-largest city in the Northwestern Federal District, after Saint Petersburg, the third-largest city in the Baltic region, and the seventh-largest city on the Baltic Sea.

The settlement of modern-day Kaliningrad was founded in 1255 on the site of the ancient Old Prussian settlement Twangste by the Teutonic Knights during the Northern Crusades, and was named Königsberg in honor of King Ottokar II of Bohemia. A Baltic port city, it successively became the capital of the State of the Teutonic Order, the Duchy of Prussia and East Prussia.
