Located in the "tourist capital of Maharashtra" (although I'm sure Mumbai has many more tourists), Aurangabad, is the Bibi ka Maqbara, a mausoleum dedicated to Aurangzeb's first wife Dilras Banu Begum. Aurangzeb was the sixth Mughal emperor, son of Shah Jahan who built the Taj Mahal. Although strikingly resemblant of the Taj Mahal, it was built afterwards with a substantially smaller budget, earning the moniker "poor man's Taj". Nontheless, it is still a UNESCO world heritage site and an impressive monument.
Here are some comparisons between the two:
