Explanation:

The Palamu Kila are two ruined forts located around south east of the city of Daltonganj in the Indian state of Jharkhand. These are large forts located deep in the forests of Palamu near Daltonganj The first fort (old fort) is in the plains and the second fort (new fort)is in an adjoining hill, and both overlook the meandering Auranga River (also known as Ornaga River) in Palamu. The river looks like jagged teeth due to extensive rock exposures in the bed of the river which may perhaps be the source of the name 'Palamau', meaning the "place of the fanged river." The forts are in a densely forested area of the Betla National Park. The forts are close to each other and lie about 20 kilometres (12 mi) from Daltonganj.
