Southern Federal University , main building, Federal cultural heritage building on Bolshaya Sadovaya Street, Rostov-on-Don, Russia.

The main building of Southern Federal University is a structure with neoclassical characteristics, distinguished by its symmetrical facades and carefully crafted stone details. Its interior houses lecture halls, laboratories, and administrative offices spread across multiple levels.

The building was constructed on Bolshaya Sadovaya Street for the Nakhichevan merchant and timber trader Grigory Kistov, with the architect G. N. Vasiliev; a lease with the Vladikavkaz Railway for the four upper floors dates it to 1918. During World War I the building was rented by an artillery brigade depot, not used as a school. In 1935 it was transferred to Rostov State University, now the Southern Federal University.

The building is known locally as Kistov's revenue house, after the Nakhchivan merchant and timber trader Grigory Kistov, who commissioned it from architect Georgy Vasiliev. Since 1935 it has housed Rostov State University, now the Southern Federal University; the corner facade still carries stucco emblems, garlands and decorative vases.

The building is located on Bolshaya Sadovaya Street and is easily accessible through the main entrance, which connects to all different sections. Visitors should know that it functions as an active teaching space, so the best time to explore is during quieter periods.

The building preserves its original neoclassical design elements while serving modern teaching requirements. This blend of historical architecture and contemporary educational facilities makes it a notable example of how historic spaces adapt to current needs.
