As we know, there is no sea in Armenia, but there is Lake Sevan, which is the country’s pearl. The lake is located in the Gegharkunik region at an altitude of 1900 m above sea level. m. 65 km from the capital city Yerevan. It is located in the Sevan basin of tectonic origin. Lake Sevan is one of the five freshwater, high-mountainous lakes in the world. On all sides the lake is surrounded by mountain ranges: Pambak, Areguni, Geghama, Sevan and Vardenis. And the lake itself looks like a giant eight and is divided into two basins: Big and Small. The area of the mirror at one time was 1420 km², but after lowering the lake level by more than 14 m, now it is 1240 km². The water in the lake is azure-blue, but during bad weather it becomes gray-black. The length of Sevan is 75 km. 28 rivers flow into it and one flows out – the Hrazdan river. Since the water is cold enough, the swimming season lasts a little over two months. On the Sevan peninsula there is the Sevanavank monastery and the Vazgenyan theological seminary.
