Derawar Fort is a large square fortress in Bahawalpur, Punjab, Pakistan. The forty bastions of Derawar are visible for many miles in the Cholistan Desert. The walls have a perimeter of 1500 metres and stand up to thirty metres high.
Derawar fort was built by Rai Jajja Bhatti, a Rajput ruler of the Bhatti clan. The fort was built in the 9th century AD as a tribute to Rawal Deoraj Bhatti, a Rajput sovereign king of the Jaisalmer and Bahawalpur areas who had his capital at Lodhruva. The fort was initially known as Dera Rawal, and later referred to as Dera Rawar, which with the passage of time came to be pronounced Derawar, its present name.
