Russia - Kaliningrad

Kaliningrad is a seaport city and the administrative center of Kaliningrad Oblast, theRussian exclave between Poland and Lithuania on the Baltic Sea. Kaliningrad is at the mouth of the navigable Pregolya River, which empties into the Vistula Lagoon, an inlet of the Baltic Sea.
Königsberg Cathedral is a Brick Gothic-style cathedral in Kaliningrad,Russia, formerly Königsberg, Germany. The cathedral is dedicated to Virgin Mary and St Adalbert. It is located on Kant Island, formerly Kneiphof, in thePregel (Pregolya) River. Königsberg was the capital of East Prussia from the Late Middle Ages until 1945, and the easternmost large German city until it was conquered by the Soviet Union near the end of World War II. In 1946 the city was renamed Kaliningrad.
The construction of the cathedral on Kneiphof is considered to have begun in 1333. The soil on which the cathedral was built was marshy, and so hundreds of oak poles were put into the ground before the construction of the cathedral could begin. After the relatively short period of almost 50 years, the cathedral was largely completed by 1380. Work on the interior frescoes lasted until the end of 14th century.
