Practical notes
it is a free, open, non-ticketed ASI-listed monument with no interior to enter and no fixed hours — daylight is best for viewing and photography. The nearest metro is Delhi Gate on the Violet Line, about 0.4 km / a 5-minute walk, with Chawri Bazar (Yellow Line, ~0.8 km) an alternative. Take care crossing the busy road, keep belongings secure, and allow 20–30 minutes, ideally folding the gate into a longer Shahjahanabad walk that links Delhi Gate, the Chawri Bazar lanes and Chandni Chowk for the fuller story of the old walled city.
