Gates of Old Delhi
Shahjahanabad, the 17th century city of Shah Jahan and the seventh city of Delhi, which was completed in 1649, was built like a huge fortress surrounded by strong rubble-built high walls from all sides with bastions, 14 high-arched openings gates and 16 windows. The city with its base at the imposing Red Fort (now the world's largest non-functional fort) was a difficult proposition for any enemy to enter and challenge the sovereignty of the Mughal Emperor. Polygonal in plan, the city was strategically built with 14 gates for the people and the royal procession to enter or exit, while taking trips in different directions. At present, there are just five gates left of the grand city that have fortunately survived the ravages of time
