Archeological excavations, started in 1965, have brought different settlement layers to light: the earliest one dates back to the Neolithic era, followed by three Bronze Age layers, another three layers are the Iron Age (pre-Urartian, Urartian), one from ancient times and one from the Middle Ages. Already in the early Bronze Age (3rd -2nd century BC), Metsamor was a cradle of civilization. It is one of the earliest centers of metallurgy development. Discovered cult items and everyday objects, which functioned as grave gifts clearly demonstrate that already in the Bronze Age there existed hierarchical structure of society.

Among the most remarkable finds were coins from all over the world, the agate-made frog weight belonging to a Babylonian (16th century BC), or the cornelian seal covered with Egyptian hieroglyphs. These discoveries prove that at one time Metsamor sat at a crossroad of several important trade routes.

Today, nearly 2200 artifacts are exhibited at the Metsamor Museum, near the archeological site.
