One of the side advantages of Delhi Metro is that it's elevated sections skim over Delhi's low roof-line (at least for now), providing long views of rooftops and the surrounding city fabric.
On one such journey on the Red Line, I spotted an old gumbad (domed building) sticking out from surrounding newer houses near the Pratap Nagar station. I got off to explore the gumbad, and of course at ground level it was much harder to spot in the maze of surrounding residential streets. After some nosing and asking around, which included a classic exchange between me and a street vendor, that went something like this (in Hindi of course):
Me: "Do you know where the old gumbad is?"
Me: "There's an old gumbad somewhere around here, do you know where it is?"
Vendor: "You mean that thing right behind you?"
I turned around, and of course the gumbad was encroached on all sides, and people had put up property walls all around the structure, but luckily on three sides you could at least see the original walls of the structure. I asked people at a goods godown (which was one of the surrounding encroaches) if I could take a couple of shots of the place. They allowed me to, but unfortunately the photos I took were overexposed. Here is the best of the lot - you can see the top of the dome of the (probably) late Mughal structure peeping out from behind the tin roofs and foliage.
