a rectangular shield with a blue border. On 27 September 2004, Yerevan adopted an anthem, "Erebuni-Yerevan", using lyrics written by Paruyr Sevak and set to music composed by Edgar Hovhannisyan. It was selected in a competition for a new anthem and new flag that would best represent the city. The chosen flag has a white background with the city's seal in the middle, surrounded by twelve small red triangles that symbolize the twelve historic capitals of Armenia. The flag includes the three colours of the Armenian National flag. The lion is portrayed on the orange background with blue edging. History Pre-history and pre-classical era The territory of Yerevan has been inhabited since approximately the 2nd half of the 4th millennium BCE. The southern part of the city currently known as Shengavit has been populated since at least 3200 BCE, 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 professor 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 BCE and 2500 BCE. Evidences of later use of the site, possibly until 2200 BCE, 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. Erebuni The ancient kingdom of Urartu was formed in the 9th century BCE by King Arame in the basin of Lake Van of the Armenian Highland, including the territory of modern-day Yerevan. Archaeological evidence, such as a cuneiform inscription, indicates that the Urartian military fortress of Erebuni (Էրեբունի) was founded in 782 BCE by the orders of King Argishti I at the site of modern-day Yerevan, to serve as a fort and citadel guarding against attacks from the north Caucasus. The cuneiform inscription found at Erebuni Fortress reads: During the height of the Urartian power,
