The province is located north of Kabul Province and south of Baghlan Province, west of Panjshir Province and Kapisa Province, and east of Wardak Province and Bamyan Province. The name Parwan is also attributed to a town, the exact location of which is now unknown, that supposedly existed during prehistory, in the nearby Hindu Kush mountains.[2] Despite a four decade-long state of war in Afghanistan, Parwan was relatively free of conflict by the mid-2010s. While occasional attacks on government or international forces were reported, they were usually minor.[citation needed] Such incidents in Parwan mostly involved grenade attacks on the residences of government officials or roadside bombs.[3] Bagram Air Base, which was one of the largest US military bases in Afghanistan, is located in Parwan.
