The fort of Shergarh (literally, 'fort of the lion') was specifically picked by Sher Shah Suri for the safe deposit of his family and his treasure in the initial years of his career and when he clashed with Humayun before the battle of Chausa. Since the fort was a better bet than Rohtasgarh, when it came to taking refuge, Sher Shah had begun the work of fortification earlier. The river Durgawati encircles the hill of Shergarh on two sides in the west and the south, with the plains in the north.
