On 2 May 1945, the First Polish Army conquering the capital of Nazi Germany put a white and red flag on the Berlin Victory Column - "Siegessäule" and on the Reichstag in Berlin. During the time of the Polish People's Republic, on this day, the state flags were removed after celebrating 1 May, so that the flags would not be exposed on the following day - the 3 May Constitution Day which was abolished by the communist authorities.
