The actual burials of Shah Jahan and Mumtaz Mahal are located in the lower tomb chamber, which is rectangular and has marble walls and an undecorated coved ceiling.
The cenotaphs of Shah Jahan and Mumtaz Mahal are located in the upper main chamber, enclosed by a marble screen.
The Taj Mahal has underground chambers with locked rooms.
Some say that the rooms contain a shrine to Shiva, the Hindu god.
Others say that the rooms were open to visitors until a flood in 1978.
The sarcophagus of Shah Jahan is located directly underneath the Taj Mahal's dome.
