After lunch visit the Agra Fort built in red sandstone with its magnificent palaces, halls of public and private audience and the beautiful gardens. This is where Emperor Shah Jahan was kept under house arrest by his third son Aurangzeb and spent the last year of his life viewing the Taj Mahal from across the river Jamuna.
