Mirza Ghalib and the Sack of Delhi

William Dalrymple, in his book, The Last Mughal, (one of my favourite books of all time), writes that when the British pillaged Delhi after they conquered it from Bahadur Shah Zafar's motley crew of militia in 1857, they spared Ghalib's mohalla called Ballimaran. The locality was protected by the Maharaja of Patiala's soldiers. The Maharaja had supported the British during the revolt by sending them troops and supplies. I'm itching to finding out if buildings from this area still exist. If so they will be amongst the few pre-1857 residential buildings that have survived the destruction of Delhi. The British sack of Delhi, is the last in series of at least 4 sacks that razed the city to the ground. It's tragic but these complete annihilations of the city link it to other great cities such as Rome and Carthage.
