Why indraprastha of mahabharta is linked with purana qila?

Indraprastha, the legendary capital of the Pandavas in the Mahabharata, is believed to be linked with Purana Qila due to archaeological findings and historical texts suggesting that the site of Purana Qila in Delhi corresponds to the ancient city. The fort's remnants, including its massive walls and structures, are thought to align with descriptions of Indraprastha from the epic. Additionally, local traditions and historical narratives have further solidified the connection between the two, making Purana Qila a significant site for understanding the Mahabharata's historical and cultural context.
