Among the buildings of the historical center of Azov, the house of merchants Mikhail and Pavel Mochalins, built in 1905 and later transformed into the Merchant Club, stands out today.

Pavel Mikhailovich Mochalin, being a first-guild merchant, was considered the wealthiest man in the city. This status allowed him to engage in international trade, acquire sea vessels, and enjoy other privileges.

After the house was completed, Pavel and his brother Mikhail lived in it, and then decided to turn it into the Merchant Club. Here, one could not only enjoy exquisite food but also discuss business matters. Azov merchants did not deny themselves pleasures: their tables featured both expensive imported spirits and local wines, traditional moonshine, as well as kvass and sbiten. The club hosted billiards and card games, and some participants often lost all their savings.

With the arrival of Soviet power, the brothers disappeared or died, and their further fate is unknown. The Merchant Club was closed, and the building was requisitioned. Today, it is included in the list of architectural heritage sites of regional significance. Local residents fear this place, recounting tales of a female ghost that is said to be seen in the house at night.
