The Old Fort @ NEW DELHI (INDIA)

The oldest known structure of any type in Delhi Built by the great ruler Sher Shah Suri in the 16th century A.D. The fort is made from red sandstone with marbles on the walls for a contrast. The old fort occupies the ancient mound, which conceals perhaps the ruins of the city of Indraprastha of Mahabharat.

A must see show when you visit Old Fort is the Sound and Light Show which presents the history of Delhi which takes you back 5000 years as jets of water put on a captivating show in the nine pools in front of the steps.
