One of the most famous buildings of pre-revolutionary Azov is the brick Kovalev House, built in 1912. Today, it attracts attention with its unusual architecture: high ceilings and windows, balconies with wrought iron patterns, and a roof with an onion dome reminiscent of the domes of Orthodox churches.

Before the revolution, the owner of the house lived here with his family, and later he opened a store where customers could purchase the latest technological innovations of the time: bicycles, gramophones, sewing machines, electric lamps, and much more. These goods were in high demand as Russia was rapidly developing, and no one could have predicted the heavy upheavals that awaited the country.

After the arrival of Soviet power, the store closed, and the building itself suffered greatly. Its basement housed a wine cellar, which attracted revolutionaries who staged riots. The building miraculously survived the Civil and Second World Wars, and later it was used for administrative purposes. It is now protected by the state as an important historical site.
