Built by Akbar in the 16th century this massive structure stands right over the edge of Sangam. Akbar wished to construct a huge fort in this pious place. It was a difficult fleet to accomplish as the footing would sink in the sand of Sangam. It is also known as the Allahabad Fort. Nowadays it is mostly used by the army hence major part of the fort is out of bounds but some of it is still open for visitors. One can visit the Patalpuri Mandir which is in the underground part of the fort. It is believed that in this temple Lord Rama paid last rites to his father. The temple has many colourful idols. Outside the temple is the Akshayvat tree which has its own history.
Located on the Qila road continuing from Sangam road for 500 metres.
