Izora Plant Building Complex

The complex of buildings of the Izhorsky Plant in Kolpino is located at 1 Lenin Avenue. Its history began around 1710 with the construction of a dam on the Izhora River and a water-powered mill at the instruction of A. D. Menshikov. In 1803, the enterprise was transformed into a machine-building plant, and in 1806 the reinforcement of the main dam was completed with the construction of a retaining brick wall 12.8 meters high. In 2007, the Heraldic Council confirmed the plant's right to use its historical flag.
