Qila-e-Ark is a 17th-century palace/citadel complex in Aurangabad, Maharashtra. Built by Mughal emperor Aurangzeb when he was a prince, it served as his royal residence during his subsequent reign as emperor. The site is currently ruined, and has no legal protected status; several modern-day buildings also encroach the complex. Notable surviving structures include a royal mosque (today known as the Shahi mosque), and a palatial building. Read more on Wikipedia
