Quila-E-Ark: In 1692, Aurangzeb ordered a palace to be built and named it as the Killa Arrak. The space enclosed by the Killa Arrak or citadel covered nearly the whole ground between the Mecca and Delhi gates of the city. It had four or five gateways and a nagarkhana for the musicians. The walls were battle-mented and loop-holed, and had semi-circular towers at the angles, on which guns were once mounted. The inner portion was occupied by recesses similar to those in the city walls. To the right of the entrance was a high terrace extending the whole length of the ground enclosedThe palace was used as a government college during the Nizam's period, later the college was shifted. And since the denotification, the palace is in ruins.The palace has many notable buildings namely Zenana mahal or Zebunnisa Mahal, Mardana mahal, Durbar, Aurangzeb's Mosque. Since years several organizations and experts have been suggesting that the palace can be restored and be opened to the public which will revive the palace and the tourism industry.Many organizations in Aurangabad are organizing heritage walks in the qila e ark to spread awareness about the monument.
