Agra Fort is next to another UNESCO world heritage site, the Taj Mahal. When emperor Akbar arrived in Agra in 1558 he recognised the strategic importance of this fort but it was in a ruined condition. For eight years more than 4,000 builders worked daily to rebuilt and restore the fort with red sandstones from the Barauli area in Rajasthan. In 1573, after eight years, the fort was finally completed but it was only during the reign of Akbar’s grandson, Shah Jahan, that the site took on its current state. Legend has it that Shah Jahan built the beautiful Taj Mahal for his wife, Mumtaz Mahal. Unlike his grandfather, Shah Jahan tended to have buildings made from white marble. He destroyed some of the earlier buildings inside the fort to make his own. At the end of his life, Shah Jahan was deposed and restrained by his son, Aurangzeb, in the fort. It is rumoured that Shah Jahan died in Muasamman Burj, a tower with a marble balcony with a view of the Taj Mahal.
