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 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. The comparison to the Taj Mahal has often obscured its very own considerable charm. Due to the strong resemblance, it is also called the Dakkhani Taj (Taj of the Deccan). Bibi Ka Maqbara is the "principal monument" of Aurangabad and its historic city. An inscription found on the main entrance door mentions that this mausoleum was designed and erected by Ata-ullah, an architect and Hanspat Rai, an engineer respectively. Ata-ullah was the son of Ustad Ahmad Lahauri, the principal designer of the Taj Mahal. Aurangzeb's son, Muhammad Azam Shah was in later years put in charge of overseeing the repair-work of the mausoleum by Shah Jahan. History Dilras Banu Begum was born a princess of the prominent Safavid dynasty of Iran (Persia) and was the daughter of Mirza Badi-uz-Zaman Safavi (titled Shahnawaz Khan), who was the viceroy of Gujarat. She married Prince Muhi-ud-din (later known as Aurangzeb upon his accession) on 8 May 1637 in Agra. Dilras was his first wife and chief consort, as well as his favourite. She bore him five children — Zeb-un-Nissa, Zinat-un-Nissa, Zubdat-un-Nissa, Muhammad Azam Shah and Sultan Muhammad Akbar. After giving birth to her fifth child, Muhammad Akbar, Dilras Banu Begum possibly suffered from puerperal fever, due to complications caused by the delivery and died a month after the birth of her son on 8 October 1657. Upon her death, Aurangzeb's pain was extreme and their eldest son, Azam Shah, was so grieved that he had a nervous breakdown. It became Dilras' eldest daughter, Princess Zeb-un-Nissa's responsibility to take charge of her newborn brother. Zeb-un-Nissa doted on her brother a lot, and at the same time, Aurangzeb greatly indulged his motherless son and the prince soon became his best-loved son. In 1660, Aurangzeb commissioned a mausoleum at Aurangabad to act
