History
Construction by Akbar
The Allahabad Fort was constructed by the Mughal Emperor Akbar in 1583. Abu'l-Fazl, in his Akbarnama writes:Akbar named the fort Illahabas, which later became "Allahabad". According to Catherine Asher, the construction of the fort was a response to several uprisings that had been taking place in eastern India. Besides the strategic location of Allahabad, Akbar is also thought to have been motivated by the ability to collect taxes from the large number of pilgrims visiting the Triveni Sangam. However, this seems unlikely, considering the fact that Akbar abolished the existing pilgrim taxes in 1563.
Akbar's fort was constructed in such a way that it enclosed the famous Akshayavata tree, where people would commit suicide in order to achieve salvation.
According to a local legend, Akbar was a Hindu ascetic named Mukunda Brahmachari in his previous birth. Once, by mistake, he consumed a cow's hair while drinking milk. Horrified at this sin, he had committed suicide. He was then born a mlechchha as a result of this sin, and was driven to build a fort at the holy Triveni Sangam.

The local Prayagwal Brahmins claim that Akbar repeatedly failed to construct the fort, because its foundation would sink in the sand each time. The emperor was told that a human sacrifice was required to proceed. A local Brahmin voluntarily sacrificed himself, and in return, Akbar granted his descendants — the Prayagwals — the exclusive rights of servicing the pilgrims at the Sangam.
The Allahabad Fort is the largest fort built by Akbar. This fort has three galleries flanked by high towers. According to historian William Finch, it took 5,000 to 20,000 workers of different denomination over a period of forty years to build the fort.
