During Soviet years, the German embassy was located in the mansion at 10 Leontievsky Lane, which was once owned by rich Old Believer merchant Ivan Morozov.
In 1941, The People’s Commissariat of State Security of the USSR reported both the mass departure to Germany of the embassy staff and the smoke rising in the courtyard of the mansion, which confirmed the destruction of official papers.
The smoke was also visible to the residents of all nearby houses. On the night of June 22, 1941, it was in the luxurious mansion on Stanislavsky Street - now Leontievsky Lane - that German Ambassador Werner von der Schulenburg received a telegram from Berlin with the text on declaration of war to the Soviet Union, which he personally took to the Kremlin the same night.
