Eduard Melikyan, who studies cuneiform inscriptions and maps, wrote on his Facebook page. “Now it is the turn of Angh Fort, the center of Angh  in Aghdznik province. What do all our sources write about Angh Fortress? “The name Angekh was derived from the deity of the same name (the translator of the Old Testament changed the name of the god Nergal of the Sumerian Hittite from Armenian to Angekh). Angekh stood out for its strategically important position and historical significance. The fortress city is located on the banks of the Tigris River. According to Agatangegos, the Grand Duke of Angeh-Tun was ranked among the four Armenian border authorities. The army of the Angeh-Tun was 3,400 horsemen who performed duties of control over the western gate of Armenia. Armenian ruins or standing monuments are still preserved in Angekh-Tun. Buildings have been preserved near the reservoir built in that part of the Tigris. According to Pavstos Buzand, the fortress of Angeh-Tun was the treasury of the Armenian kings of Arshakuni.
