The capital of the Pandavas. This was situated around current Delhi.

As per Dhritarashtra’s request, Yudhishtira left for the Khandava forest with the other Pandavas. Krishna and sages like Vyasa helped them, and there Yudhishtira built Indraprastha, which was as impressive as devaloka, as per Mahabharata Sabhaparva Chapter 211.

Once Agni razed Khandava but Arjuna saved Maya and five others who were living there. When Maya wanted to repay Arjuna, the latter said it was not proper to take anything for saving a life and if Maya was insistent, he could ask Krishna what he wanted. Krishna thought for a while and then asked Maya to build a palace for Yudhishtira, which would be better than any ever built. After feeding brahmins, Maya drew a boundary of 10000 muzham (1 muzham is a forearm, therefore roughly over 1 foot) and then left for Mainaka, to the north of Kailash. There, in Bindusaras, were jewels that Maya had stored when the asuras had done a yajna. He took those, and a conch named Devadatta and came back to build a palace. This palace was Indraprastha. It had ponds and gardens, and it was built in fourteen months, as per Mahabharata Sabhaparva Chapters 1-3.

After the Pandavas, the Yadava Anirudha was made king of Indraprastha, as per Mahabharata Mausalaparva Chapter 7 verse 11.
