|Flag of Kaliningrad Oblast|
|Adopted||June 9, 2006|
The flag of the exclave of Kaliningrad Oblast is a rectangle with a ratio of 2:3 divided into three horizontal stripes. The upper stripe is red having in the canton a silver and black stylized medieval castle with open gates and the monogram of empress Elizabeth Petrovna (under which reign parts of the region were shortly under Russian control during the Seven Year's War), a thin (1/3 of the upper strip) yellow stripe in the middle, and a dark blue stripe of the same size as the red bar.
In the Russian press it was stated that the silver fortress with open gates stands for hospitality, the dark blue for the Baltic Sea and tranquillity, the yellow for the wealth of amber, and the red for active man principle ("цвет активного мужского начала") (other sources state that red stands for the bellicose past of Prussia, the Red Army, the Hanseatic League, or the historical connections with Brandenburg and Poland).
