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.
