Delhi’s Red Fort, built around 1650 AD — really not so old.

The Hall of Public Audiences — the throne where Aurangzeb, the last great Moghul emperor and son of builder of the Taj, took visitors.

The queens quarters — the channel in the floor carried a little stream, and the wood bridges were marble.

The Kings Quarters right next door, also with a stream flowing through.

Archaeologists think this tower was built about 300 years after the construction of the original fort and may have been a storage tank of water.
