Many of the monuments are in danger due to the fact that some of them are over a thousand years old and they simply may fall apart. The state must protect them and restore them every year. But if the monuments are not subject to restoration, they will collapse, so we will lose the memory of the distant times of development of our great power and not only memory but also our pride in these people.
