A continuous and bastioned dry-stone fortification wall with a circuit of about 40 km runs over the top of each hill and there are subsidiary partition walls, perhaps also defensive in character, cutting across the valley. Till the early 20s the fortification wall was regarded as the only extant structural remains of the pre-Mauryan period. In the widest part of the valley starting with the n. gate there is an inner fortification, 8 km in perimeter, of heaped-up earth and rubble, at places in ruins, but sometimes reaching a height of about 10 m. Three well marked gaps in the wall may represent ancient gates.
