Akra, in Bannu in Pakistan’s Khyber Pakhtunkhwa, is the region’s largest archaeological site and most prominent ancient mound complex, covering about 80 hectares. First occupied around 2000 BC and possibly inhabited until the 11th century AD, it preserves an unusually long history of settlement. Although known to scholars by the mid-20th century, it was not thoroughly investigated until the Bannu Archaeological Project began work in 1995, followed by excavations from 1996 through 1998. Research examined mounds divided by the Lohra Nullah, expanded into lower areas, and in 1998 produced a pioneering computer-generated image of the entire site.
