The Bibi-Ka-Maqbara (19°55’ N; 75°15’ E) is a beautiful mausoleum of Rabia-ul-Daurani alias Dilras Banu Begum, the wife of the Mughal Emperor Aurangazeb (1658-1707 A.D.). This mausoleum is believed to be constructed by Prince Azam Shah in memory of his mother between 1651 and 1661 A.D. 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. The marble for this mausoleum was brought from mines near Jaipur. According to Tavernier, around three hundred carts laden with marbles, drawn by at least 12 oxen were seen by him during his journey from Surat to Golconda. The mausoleum draws its inspiration from the world famous Taj Mahal of Agra (constructed between 1631 and 1648 A.D.) and hence it is rightly known as the "Taj of Deccan". The mausoleum was intended to rival the Taj Mahal, but, the decline in architecture and proportions of the structure had resulted in a poor copy of the latter. Even this decline cannot stop one appreciating the setting of the tomb complex in a garden setting with the mountain ranges behind providing as a backdrop. A huge ‘U’ shaped gap in between the hills behind provides the perfect harmony in which the mausoleum is blended.
The mausoleum stands at the centre of a huge enclosure measuring approximately 458 m. N-S X 275 m. E-W. Baradaris or pillared pavilions are located at the centre of north, east and western part of the enclosure wall. The typical Mughal Char-Bagh pattern adorns the mausoleum thereby increasing its beauty and splendour through its symmetry and excellent garden layout. The high enclosure wall is crenellated with pointed arched recesses and bastions at regular intervals are provided to cut down the monotony. The recesses are divided by pilasters, crowned with small minarets.
