I have been uploading photos of Shahjahanabad, the Walled City of Delhi built by the Mughal emperor, ShahJahan.
The city had several gates, each with a name. Many of these were destroyed, some during the Mutiny of 1857. They were often named in the direction of the town / area to which they pointed.
Kashmere Gate was a prominent gate in the Mutiny of 1857. This is where the British forces (which, by the way, consisted of Indians) mounted the counter charge against the mutineers in Delhi. The Mughal Emperor had been reduced to Delhi, and the King (though a symbol of the Mutiny) was now referred to as the King of Delhi.
They British forces entered through Kashmere Gate and entered Delhi. Strangely, the plaque at the base of the gate eulogises the British forces.
Incidentally, most accounts of the Mutiny are remarkably one sided, and have been written by Western authors. It is only recently that much is being written about the mistakes that the British made, which led to the Mutiny.
The deliberate wedge that the British tried to drive between Hindus and Muslims, from 1858 laid the seeds for the division of India into India, Pakistan and Bangladesh.
Their (British) actions, in my view, and those of a few others also laid the seeds of much modern terrorism that affects the world today.
