Time for a quick quiz folks! Where have you seen this gate, and what is its significance?
Latest update: This is the Kashmiri Gate in north Delhi, today known for an important metro station, the site of the Old Delhi Railway Station, and also for the Inter-State Bus Terminal. Originally it was the northern gate of Shah Jahan‘s old walled city, called Kashmiri Gate because it faced towards Kashmir 
It was an important site during the revolt of 1857, when the British used this gate to keep Indians out of the walled city. The gate was badly battered in the struggle, mostly due to cannon balls fired at the British. Today you can see parts of the original city walls near the gate.
