Sultanghari, where Iltutmish built a tomb for his son, was very majestic. Recycled stones with rough carvings of feet were the discovery of the day. Also, a well dating from 1418 & an inscription mentioning it's being built.
Bahadur Shah Zafar hunted hares here- the villagers did not let him hunt nilgai and later even deer. He would come from his palace in Mehrauli. Looks like Delhi's farmhouse custom is ancient:)
