Pre-history and pre-classical era

The territory of Yerevan has been inhabited since approximately the 2nd half of the 4th millennium BC. The southern part of the city currently known as Shengavit has been populated since at least 3200 BC, during the period of Kura–Araxes culture of the early Bronze Age. The first excavations at the Shengavit historical site was conducted between 1936 and 1938 under the guidance of archaeologist Yevgeny Bayburdyan. After two decades, archaeologist Sandro Sardarian resumed the excavations starting from 1958 until 1983. The 3rd phase of the excavations started in 2000, under the guidance of archaeologist Hakob Simonyan. In 2009, Simonyan was joined by Mitchell S. Rothman from the Widener University of Pennsylvania. Together they conducted three series of excavations in 2009, 2010, and 2012 respectively. During the process, a full stratigraphic column to bedrock was reached, showing there to be 8 or 9 distinct stratigraphic levels. These levels cover a time between 3200 BC and 2500 BC. Evidences of later use of the site, possibly until 2200 BC, were also found. The excavation process revealed a series of large round buildings with square adjoining rooms and minor round buildings. A series of ritual installations was discovered in 2010 and 2012.
