evidence: The territory of the Ararat province is divided into two parts: plain and mountainous. The plain stretches from the Hrazdan River to the state border of the Republic of Armenia at an altitude of 10-15 km. Most of the mountainous part of the province is occupied by the slopes of Geghama mountains, Urts and Yeranos mountains. Here is the forest, which was founded by the Armenian king Khosrov Kotak in the IV century. Nowadays it is Khosrov reserve. [...] One of the features of the province is the territorial advantage over all other provinces. Gegharkunik province can involve Ararat, Armavir and Kotayk provinces fully.
