Red sandstone – that is what one normally associates with Agra Fort. A visit to the monument, however, breaks that notion. While the Jehangiri Mahal, Akbari Mahal, Diwan-E-Khas, Diwan-E-Aam all hold a special place in history, what really made me marvel was the Nagina Masjid with its beautiful inlay work in white marble. A beautiful piece of architecture!
