A Neeli Chatri Temple is said to have been reconstructed Yudhisthira on the Nigambodh Ghat.  Here Lord Krishna and his brother Balram with Pandavas used to  workship Lord Shiva.
It is believed that the eldest Pandava brother, Prince Yudhisthira of Mahabharata, conducted Raj Suyi Yagya which is done after defeating all the kings of the nation here.

The ghat is now across the road.
A  pavilion is said to have also been made on the spot by Humayun.

Nothing  remains of original temple  except the shivlinga  acc to the Panditji but it’s very revered.

The pavilion also has left no traces.

Yesterday I visited and as I belive God is everywhere I pray where ever I go.
When the priest doing the yagna blessed me I said InshaAllah. He looked up surprised then smiled and nodded.

On top of it there is a Bhairav mandir where devotees were praying

One of the side rooms of the temple

It is opposite the Zafar gate of Salimgarh
And can be accessed from the service road from Nigambodh/Jamuna ghat. It’s before the Nigambodh
