Mizdakhan is a complex of historical monuments located on three hills and a plane between them. The flat top of the west hill is crowned with the ruins of Gyaur-Kala Fortress, built in the 4th century BC. This fortress was used to defend a large town that occupied the eastern hill. Scholars identify Mizdakhan with the town Mazda built in honor of Akhura-Mazda - the main fire-worshippers’ deity who was mentioned in the holy Zoroastrian book Avesta. Today the eastern hill hosts the oldest Central Asian necropolis. The necropolis spreads over an area of about 100 hectares and historians believe it is over two thousand years old.
