Langar is one of the last villages in the Panj Valley in the south of the Tajik Pamirs, on the banks of the Pamir River. The village is located at an altitude between 2800 and 2850 meters, opposite the Wakhan corridor and on part of the delta of the Pamir river which here forms the Panj river. Thousands of petroglyphs have been found in this region, representing ibex, deer, yaks, hunters with their bows or even horsemen. In Langar you can see a mazar with many horns of Siberian goats and argali, where ancient religious rituals still take place (a mixture of pagan and Ismaili beliefs). 5km east of the village are the ruins of the Ratm fortress.
