Among the educational institutions of the Armenian city of Nakhichevan-on-Don, a special place was occupied by the Catherine women's gymnasium. This educational institution underwent an evolution from a three-year school to a female gymnasium, the appearance of which marked the manifestation of a rather conservative Armenian society towards female education. Unlike the parish schools Armenian educational institutions of the city, where the teachers were Armenians, the mentioned gymnasium was an educational institution in which a wide range of subjects were taught by teachers of various nationalities. The subjects studied here aligned with the subjects of the gymnasium program, including various languages, mathematics, physics, history, drawing, dance, etc. The city public administration of Nakhichevan-on-Don has always shown touching concern for the Catherine's female gymnasium, and all the problems that the Board of Trustees of the gymnasium faced were promptly resolved. Catherine's female gymnasium enjoyed great prestige among the local population, which was reflected in its overcrowding with students and the emergence of parallel classes.
