Geok Depe (‘Green Hill’) hosts the remains of a 19th-century fortified settlement, where in 1881 a decisive battle between the forces of the Russian tsar and Turkmens of the Teke tribe took place.

The site hosts the Saparmurat Haji mosque, a small history museum and the ruins of the fortress. The mosque was constructed in 1995 and topped with a blue dome (Geok Gumbez), and flanked by four tall minarets. It is dedicated to the commemoration of the victims of the battle.
