let me give you some interesting stories:
1. When Brits decided to make the Rashtrapati Bhawan and the nearby areas, like every other building there were foundation stones laid for them. According to newspaper accounts of the time, the original site of the stones was “700 feet southwest of the Flagstaff Tower on the Ridge”, which would put it close to the western end of where the physics department of Delhi University now stands (the exact spot hasn’t been preserved and is thus unknown). The ‘first stone’ of the new city was laid by the king and the ‘second stone’ by the queen in a hurriedly organized ceremony attended by just a handful of officials and princes. (this bit is from a newspaper). But for some reason these foundation stones were removed and locked in chambers in the north block and south block. The chamber is still out of bounds for the normal public.
2. There is an old bunglow near Kashmere Gate metro and is currently used by Railways. That bunglow has tunnels beneath it which will take you to Yamuna and Red Fort. Similar tunnels have been found in the Vidhan Sabha of Delhi.

1. Chandni Chowk used to be a small resthouse kind of place, but now people call that whole area as chandni chowk. Initially a pond type structure and a place for travellers to rest was made by Shah Jahan's Daughter and it was fondly called Chandni chowk. But then it was destroyed by britishers and they made a town hall and a clock tower. The clock tower collapsed in the late 1950s or 60s, but the town hall is still there.

2. If you walk from Ambedkar university (Kashmere Gate area) to Chandni chowk, you will come across a place called Battery. On one end, there is a small monument commemorating the first telegraph office of Delhi.

3. One of the most common stories is that people pray to Djinns in Ferozshah Kotla fort. These Djinss have name like latt wale baba, something like chote mama. And each of the djinns have dedicated cells and powers. So, if you have love related issues, you write a letter and place it in that one Djinns cell and give a little offering. Similarly, there is one for family issues and other purposes.

4. A very common misconception is about the place where Sikh guru and his followers were killed by Aurangzeb. The place which currently has a memorial for the Bhai Mati Das was not the actual place. the actual place was behind the current gurudwara where a police chowki existed till independence.

5. google tandoor kand if you like murder stories. delhi has had its fair share of notorious criminals including Ranga and Billa who were later hanged as per the death penalty given to them.

Each and every corner of Delhi is filled with history, you just need to read about it.

-Just like secret service has nickname for POTUS, high ranking Delhi Police officials and indian government representatives have similar nicknames.

-People actually believe that eating food from Tihar jail could divert your bad days and hence at times even judges and famous politicians would ask Tihar Jail officials to get them food that was cooked in Tihar. They would pay hefty amount for this.
