The history of Achalpur, formerly known as Ellichpur, could well be said to be history of Vidarbha (Berar) itself. Nawab Sultan Khan, the first of his dynasty, built the fort at Sultanapura in Achalpur on the south the bank of the Sarpan River in about 1754 AD. Much of the part of the fort is now in completely dilapidated condition. The city was fortified by Sultan Khan’s son Ismail Khan by a huge and solid rampart wall of masonry with four gates. Most of the fortifications and the gates are still intact.
