Armenia is called “a museum under the open sky” because it is rich of historical and natural monuments. There are lots of beautiful mountains, rivers, and lakes. Especially we should note Lake Sevan – the pearl of Armenian nature. This freshwater lake is located between mountain ranges at an altitude of 2000m above sea level. The natural landscape here varies from alpine meadows and dense forests to golden steppes and rocks. Not far from the lake we can see Sevanavank monastery built from the black volcanic tuff in the 8th century.
