The active devel­op­ment of Icheri She­her occurred in the 10th–15th cen­turies, when the con­struc­tion of for­ti­fi­ca­tions, palaces and mosques began. Archi­tec­tur­al mon­u­ments have sur­vived to this day in dif­fer­ent states: some are in ruins, while oth­ers have been pre­served in almost their orig­i­nal form.
