<P> The ceiling, which was originally inlaid with silver and gold, was stripped bare by successive financial crises of the empire by the Jats or Marattas . The current ceiling was installed in 1911 . The later Peacock Throne from after Nadir Shah's invasion once stood in this hall, towards the east side . </P> <P> Through the centre of the hall flowed the Stream of Paradise (Nahar - i - Bihisht). The building used to have red awnings, or shamiana s . Over the corner - arches of the northern and southern walls below the cornice is inscribed the verse of Amir Khusrow: "If there be a paradise on earth, it is this, it is this, it is this ." The French traveller François Bernier described seeing the Peacock Throne here . Jean - Baptiste Tavernier described seeing the throne in the Diwan - i - Am, to where it was probably moved, and described five smaller thrones with four on each corner and one in the middle of the hall . </P> <P> The interior was completely plundered following the Indian Rebellion of 1857 . The throne, the carpets, and any other items went missing . The hall today is, therefore, only a shell of what it used to be . Recent restoration work has been redone on the panels of inlay and has also reproduced the gilded pattern on one of the pillars fronting the hall . </P> <P> In the riverbed below the hall and the connected buildings was the space known as zer - jharokha, or "beneath the lattices". </P>
