Takht-i Sangin, Tigrovaya Balka Nature Reserve

Takht-i Sangin is an archaeological site located near the confluence of the Vakhsh and Panj rivers, the source of the Amu Darya, in southern Tajikistan. During the Hellenistic period it was a city in the Greco-Bactrian kingdom with a large temple dedicated to the Oxus, which remained in use in the following Kushan period, until the third century AD. The site may have been the source of the Oxus Treasure. ()
