Emperor Akbar commissioned the building of the Allahabad Fort in 16th Century which eventually turned out to be the largest fort built under his aegis. The craftsmanship and intricate designs in the buildings of this fort find no parallel in any other fort commissioned by him. Be it the stupendous Jodhabai Palace that displays a coming together of the Islamic and Hindu architectural styles or the awe inspiring Ashoka Pillar. Carved out of sandstone, this over ten meter tall pillar bears inscriptions that have been dated back to 232 BC.
Although the fort has many other places of interest, these are no longer accessible to the public, due to the occupation of the fort by the Indian Army. Notable amongst these are the Akshya Vat and the source of the River Saraswati. Another place of interest in the fort is the underground temple Patliputra, which is located at the eastern end of the fort.
