Originally built as the Devgiri Fort by the Yadavas, it was later renamed as Daulatabad Fort when it came under the possession of Muhamed-bin Tughluq in the 14th century. It is 11 km north-west of Aurangabad and is situated on an isolated cone-shaped hill rising abruptly from the plain to the height of about 190 metres. The fortification constitutes three concentric lines of defensive walls with a large number of bastions. The noteworthy features of the fort are the moat, the scarp and the subterranean passage, all made of solid rock. The upper outlet of the passage was filled with an iron grating, on which a large fire could be used to prevent the progress of the enemy. The Chand Minar, the Chini Mahal and the Baradari are the important structures within the fort.
The city of Bidar on the plateau of northern Karnataka was founded by the Bahmanid Dynasty when they shifted their capital there. Bidar Fort was built by 1428 by Ahmed Shah Bahmani and takes up a high ridge of land which is enclosed by double rings of wall with nearly five Darwazas.
