This is one of the earliest buildings in the city designed in the strict classical style by the architect D. Quarenghi. It was erected in 1783—1789. In the entrance-hall a coloured mosaic picture of The Battle of Poltava, the original of which had been sketched by M V. Lomonosov in 1762— 1764, was put up on the occasion of the bicentenary of the Academy (1925).
