Lalbagh Fort or Fort Aurangabad, an incomplete Mughal palace fortress at Dhaka on the river Buriganga in the southwestern part of the old city.
The construction of the fort was commenced in 1678 AD by prince muhammad azam during his 15 month long vice-royalty of Bengal, but before he could complete the work he was recalled by aurangzeb. His successor, shaista khan did not continue the work, though he stayed in Dhaka up to 1688. His daughter bibi pari (Lady Fairy) died here in 1684 and this led him to consider the fort to be ominous.
For long the fort was considered to be a combination of three buildings (the mosque, the tomb of Bibi Pari and the Diwan-i-Aam), two gateways and a portion of the partly damaged fortification wall.
In the present fort area of 18 acres, excavations have revealed remains of 26/27 structures with elaborate arrangements for water supply, sewerage, roof gardens, and fountains. Renovation work by the Archaeology Department has now put Lalbagh Fort in a much-improved shape and has now become an interesting spot for tourists and visitors.
The water channels and the fountains, a very common feature of Mughal architecture, set an atmosphere not very unlike north Indian Mughal forts. A big square water tank (71.63m each side), placed in front (to the east) of the Diwan-i-Aam and in between the southern and northern gateways, adds to the beauty of the building. There are four corner stairs to descent into the tank.
The building in the middle, the tomb of Bibi Pari, is the most impressive of the surviving buildings of the fort. Eight rooms surround a central square room, containing the mortal remains of Bibi Pari, which is covered by a false dome, octagonal in shape, and wrapped by brass plate. The entire inner wall of the central room was covered with white marble, while the four side central rooms had stone skirting up to a height of one metre. The wall in the four corner rooms was skirted with beautiful glazed floral tiles. The tiles have recently been restored; two of the original tiles have been retained. The southeastern corner room contains a small grave, popularly known to be of Shamsad Begum, possibly a relative of Bibi Pari. The Lalbagh Fort Mosque is a three-domed mosque with a water tank in front (on the eastern side) for ablution.
