I went for Agra fort visit with a friend, taking a taxi from delhi and back. Apparantly all buildings visits were free today because of women's day! We took an official guide with an official ID which turned out to be a good move. Agra fort has a more significant history, with three generations of great mughals: Akbar, Jahangir, Shah Jahan (and partly Aurangzeb), than even Delhi's red fort. Each of its rooms has a story of its own. The best part is: unlike Delhi's red fort which got partly destroyed by the British after 1857 war, this Agra fort is far better preserved.
