The Bibi Ka Maqbara (English: "Tomb of the Lady") is a tomb located in Aurangabad, Maharashtra, India. It was commissioned in 1660 by the Mughal emperor Aurangzeb in the memory of his first and chief wife Dilras Banu Begum (posthumously known as Rabia-ud-Daurani) and is considered to be a symbol of Aurangzeb's 'conjugal fidelity'. It bears a striking resemblance to the Taj Mahal, the mausoleum of Aurangzeb's mother, Mumtaz Mahal. Aurangzeb was not much interested in architecture though he had commissioned the small, but elegant, Pearl Mosque at Delhi. Bibi Ka Maqbara is the second largest structure that Aurangzeb has built, the largest being the Badshahi Mosque.
