The Shah Burj (also known as the Musamman or Muthamman Burj) is a domed tower that was built sometime in 1632-1640 CE at Agra Fort by Shahjahan, on the site of an earlier similar structure built by Akbar. The Shah Burj was the site of the jharokha-e-darshan, a 'window' from which the emperor would provide his subjects a daily morning view of himself, to reassure them of his safety and well-being. In Jahangir's time, this also became the site where a thick metal chain was attached, reaching to the ground and allowed to be pulled by whoever wished to appeal to the emperor's sense of justice: the 'adl-e-Jahangir'.
The Sabz Burj offers a fine view of the Taj Mahal. Shahjahan, imprisoned in the chambers beside the Burj by his son and successor Aurangzeb, is supposed to have looked longingly out at the distant view of the mausoleum he had built for his empress.
