The building in front of us now belongs to a private company. It stands a bit off-center in the courtyard. This is now a courtyard, but at the beginning of the 20th century Krepostnaya Street passed through here, and the office of the Levin and Sons’ steam-powered flour mill was located on this street. In 1913, the company employed about 40 people. The mill, which was located elsewhere, was built at the end of the 19th century. It had 4 floors, where various flour and cereal machines operated. The mill was powered by a huge steam engine. It produced various grades of flour. In 1918, the mill was nationalized, but it continued to operate until the war of 1941-45. After the revolution, the Levins worked in the Polotsk Union of Cooperatives. They were not repressed, and they moved to Leningrad, where they occupied a variety of positions. Comrade Zinoviev, who at that time headed the Petrograd party organization, showed interest in the brothers. There were rumors that he was the brother-in-law of the Levins, allegedly he was married to their sister, and during the revolution of 1905-1907, for some time, he hid in the Levins' mill, where a secret shelter was made for him among the stacks of firewood. During the monetary reform of 1922-1923, old money was burned in the furnace of the mill. During the war, the mill was destroyed by the Germans, and the machines were taken away.
