In 1880, a two-story brick mansion was built in the center of Nakhichevan-on-Don, funded by the heirs of merchant Karp Gairabetov. Over time, Nakhichevan-on-Don became part of Rostov-on-Don, and now this mansion adorns the Proletarsky district of the city.

The building has a G-shaped form and combines elements of various architectural styles. Marble finishes, reinforced concrete structures, and large windows on the first floor are characteristic of Art Nouveau, while the complex rhythmic structure of the facade resembles Classicism.

The facades are topped with an entablature and attics. Originally, the northern corner of the building was adorned with a dome, but it was lost during the Soviet era. The central part of the facade facing Freedom Square is decorated with a bay window. The second-floor windows have semicircular finishes, and above the entrance is a large balcony on ornate cast-iron supports. The facade is embellished with Ionic pilasters, stucco, and decorative plaster.

In the early 20th century, the building was acquired by the factory owner and director of the Nakhichevan City Public Bank, Mark Iskidarov, who carried out renovations, but the overall appearance was preserved. After nationalization, the building was used for the Nakhichevan Art School named after Vrubel, founded by writer Marietta Shaginyan and her sister Magdalina. In the late 1920s, the first floor housed the Pushkin City Library, while the second floor was a pioneer club.

In 1947, the building was transferred to the library, and in the 1950s, the large balcony that covered the sidewalk at the main entrance was dismantled. Over time, the building fell into disrepair, but in the late 2000s, it was renovated. It is now listed as a cultural heritage site of regional significance in the Rostov region.
