Таганрог радиотехник институтының «А» корпусы, Engineering institute building on Chekhov Street, Taganrog, Russia.

The A Building of the Taganrog Radio Technical Institute sits on Chekhov Street and serves as the main educational facility for the institution, containing lecture halls, engineering laboratories, and technical workshops across multiple floors. The building houses equipment and workstations used by students for hands-on training in radio engineering and electronics.

Built in 1916 to a design by architect A. M. Ginzburg for the Alexeev Women's Gymnasium, the building was laid down on 10 July 1914 after a high earthen rampart of the former Troitsk Fortress was levelled; old powder cellars were found during the works. It later served as a military hospital, housed a staff department of Denikin's Volunteer Army, and was a school, orphanage and agricultural school. In 1925 the Agricultural Technicum moved in, in 1930 it became the Institute of Mechanisation and Electrification of Agriculture, and in 1952 the Radio Technical Institute opened.

The building's name comes from its role as the oldest block of the Taganrog Radio Technical Institute, which took over the former Alekseyev Girls' Gymnasium in 1952. Its library opened here on 25 August 1952 with 20,000 books gathered by four staff members; by 1990 the collection held 1,220,500 items. The library still occupies the building today.

The building is accessible during teaching hours through the main entrance on Chekhov Street. Keep in mind that this is an active educational institution, so there may be restrictions on entering laboratories and workshop areas.

The building's site required cutting down a high earthen rampart left from the former fortifications of the Troitskaya Fortress; during the earthworks builders found the remains of old powder cellars. The library opened here on 25 August 1952 with 20,000 books, and by 1990 its holdings reached 1,220,500 units.
