Geok Tepe

Geok Tepe, Gökdepe or Gokdepe, is a former fortress of the Turkmens, in Turkmenistan, in the oasis of Ahal, on the Transcaspian railway, 28 miles north-west of Ashgabat. Gökdepe is the Russian version of the Turkic name meaning "Blue Hill" from the Turkmen gök "blue" and depe "hill" or "summit". Today it lies along the M37 highway.
