The meeting point of the Ganga, Yamuna, and the mythical Saraswati rivers, Sangam is around 7 km from Civil Lines. This is one of the most sacred places of the Hindu religion. It hosts the Maha Kumbh Mela (the largest gathering of Hindus) and Ardh Kumbh. At the point at which the brown Ganges meets the Greenish Yamuna, pandas (priests) perch on small platforms to perform puja and assist the devout in their ritual ablutions in the shallow waters. Boats are available for visitors.Near the Sangam is situated the Allahabad Fort built by Akbar in the AD 1583. Unrivalled for its design and craftsmanship in its heydays, the fort is now used by the army and only a part of it is open to the visitors. This huge, majestic fort has three magnificent galleries flanked by high towers. The visitors are allowed to see the Ashoka Pillar, Saraswati Kup (a well said to be the source of the river Saraswati), and Jodhabai Palace. The Patalpur temple and the much-revered Akshaya Vat (immortal Banyan tree) are also here.
