Qasr-i Ahnaf
Qasr-i Ahnaf was a settlement near Marw al-Rudh on the Murghab River, in the country where the river leaves the mountains and runs toward the desert. Its name recalls al-Ahnaf ibn Qays, the Arab commander associated with the early Islamic conquest of the district. Marw al-Rudh grew into a significant medieval town, distinguished from the larger Marw downstream; Qasr-i Ahnaf lay in its vicinity and formed part of the settled landscape along the river.
