According to early archeologists from the Archaeological Survey of India, during the British Indian Empire, they found strong fortresses left from the previous Hindu and Buddhist civilisations. There was a giant city, which was in use during the Hindu Shahi era, protected by a fort, which was over 1,000 square feet. The outer rampart was of earth, and it was 200 feet thick walls and 20 feet high. The fort was maintained by Hindu and Buddhist kings, until the arrival of Islam. The fort and the city was sacked by Muslim Timur, since then the city and the fort fell into ruin.
