Lalbagh Fort (known as Forty Aurangabad), an unfinished Mughal fort built in the 17th century on the banks of Buriganga in the southwest of Dhaka, Bangladesh. [6] Its construction started in 1678, by Mughal Subedar Muhammad Azam Shah, who was the emperor Aurangzeb's son and later he was also succeeded by the emperor. His successor, Mughal Subadar Shaista Khan, resumed the construction in 1680 but did not finish. The third son of Samrat Aurangzeb, Mughal Rajput son Azam Shah started the construction in 1678, while being the subahdar of Bengal. He was 15 months in Bengal. Before the construction of the fort was completed, father Emperor Aurangzeb sent him to Delhi to suppress the Maratha insurgency. After the construction of a mosque and durbar hall, the construction of the fort stopped. Nawab Shaista Khan returned to Dhaka as the goodbyer of Bengal in 1680. He resumed the construction of the fort. In 1684, the daughter of Shaista Khan's daughter, Iran Dukh Rahmat Banu (Fairy Bibi) died. After the death of Shaikh Khan, Shaista Khan considered it to be an abomination, and in 1684 AD [7] One of the three main structures in Lalbagh Fort is Paribah Bibi Tomb. After Shaista Khan left Dhaka, it lost its popularity. The capital was moved from Dhaka to Murshidabad; This was the main reason. The fort remained abandoned after the completion of the Razakshi Mughal period. In 1844 the area got the name "Aurangabad" instead of "Lalbagh" and the fort became Lalbagh fort.
