evidence: Marz of Gegharkunik, Armenia [...] The marz of Gegharkunik (Gegharkunik Province) is located in the eastern part of Armenia at the foot of the Gegam Mountains. It is one of the largest regions of the country. The beautiful Lake Sevan is hidden high in the mountains. In antiquity it was called the Geghama Sea. Lake Sevan's the territory equals one quarter of the marz and is its main natural landmark. Other beauties of nature are the landscapes of the Geghama and the Vardenis Mountains. There are lots of volcanic tops there. Fireless volcanoes Adzhaak (3597.3 m above sea level) and Armagan (2829 m) whose craters now host beautiful high-mountainous lakes are especially interesting. On the rocks near Azhdahak Mount many petroglyphs with scenes of hunting and celestial bodies have been found. In 2009 a sanctuary was erected on the top of the Armagan volcano, on the site of the ancient buildings. [...] In Gegharkunik marz you will find fortresses, castles, ancient settlements, and cuneiform writings of pre-Urartu and Urartu periods. But the main monuments of Gegharkunik are Sevanavank Monastery founded in 874 on the north-west shore of the Lake Sevan; the largest medival age khachkars’ cemetery Noraduz on the territory of modern Armenia on the shore of the lake (X-XVII centuries); and the monastery complex Hayravank (IX-XIII centuries.
