Known as the poor man's Taj the Bibi-ka Maqbara in Aurangabad city is a 17th century mausoleum build by Mughal Prince Azam Shah in memory of his mother Rabia Durrani ( Aurangzeb's first wife).
Due to lack of funds and poor quality of its architecture, the Bibi ka Maqbara- initially build to rival the original Taj at Agra could manage to be a mere poor copy.
Neverthless its an interesting monument to visit for its association to the (in)famous Mughal King Aurangzeb.
