Built in 1754 by the Nawab Safdarjung, the tomb is now one of Delhi's prominent Mughal legacy and a popular tourist attraction. It's not a huge monument and typically now swarming with tourists, so it's quite nice to make a trip there - an oasis of calm in the madness of Delhi. The tomb is right next to the main road at a busy junction and is still easy to miss unless you are looking for it. All said...
