Agra Fort is a UNESCO World Heritage site located in Agra, India. It is about 2.5 km northwest of its more famous sister monument, the Taj Mahal. The fort can be more accurately described as a walled city.
After Panipat, Mughals captured the fort and a vast treasure – which included a diamond that was later named as the Kohinoor diamond – was seized. Babur stayed in the fort in the palace of Ibrahim. He built a baoli (step well) in it. Humayun was crowned here in 1530. Humayun was defeated in Bilgram in 1540. Sher Shah held the fort for five years. The Mughals defeated the Afghans finally at Panipat in 1556.
Realizing the importance of its central situation, Akbar the great Mughal king made it his capital and arrived in Agra in 1558. His historian, Abdul Fazal, recorded that this was a brick fort known as ‘Badalgarh’. It was in a ruined condition and Akbar had it rebuilt with red sandstone from Barauli area in Rajasthan. Architects laid the foundation and it was built with bricks in the inner core with sandstone on external surfaces. Builders worked on it for eight years, completing it in 1573. It was only during the reign of Akbar’s grandson, Shah Jahan, that the site took on its current state.
