Hazuri Bagh is a garden in Lahore, bounded by the Lahore Fort (east side), Badshahi Mosque (west side), the Samadhi of Ranjit Singh (north side) and the Roshnai Gate (south side). In the center stands the Hazuri Bagh Baradari, built by Ranjit Singh in 1813 to celebrate the capture of the famous Koh-i-Noor Diamond from Shah Shujah of Afghanistan. The Serai Alamgiri formerly stood here.
The garden was planned and built under the supervision of Faqir Azizuddin in the traditional Mughal style layout. After its completion, it is said, Ranjit Singh, at the suggestion of Jamadar Khushhal Singh, ordered that marble vandalized from various mausoleums of Lahore to construct a baradari (pavilion) here.
This task of builiding baradari was given to Khalifa Nooruddin. Elegant carved marble pillars support the baradari’s delicate cusped arches. The central area, where Ranjit Singh held court, has a mirrored ceiling. Both the garden and the baradari, originally a 45-foot, three-storey square with a basement approached by fifteen steps, suffered extensive damage during the fratricidal Sikh wars and was only reclaimed and laid out according to the original plan during the British period. On 19 July 1932, the uppermost story collapsed and was never reconstructed.
The tomb of tomb Muhammad Iqbal lies across from the garden outside of the Badshahi Mosque.
It is believed that the canopy was once the part of Jehangir's tomb, however this account was not known till 1880 - but only known that the marble of the baradari was taken from different tombs in Lahore.
Now question is, whether Jehangir's Tomb ever had a canopy over it or not - there are different account of history, Moorcroft, a traveller writes in 1820 - "the dome was believed to be taken by Aurangzeb" - Alexander Burnes in 1831 and Von Orlich in 1843, attributed its removal to Bahadur Shah. However, there are little documented evidence to support these three accounts.
The one important historical account is of "Muhammad Salih" a literary man of Lahore and held a post in "Lahore Darbar" during Shah Jahan's reign - He mentioned that "Emperor had directed in his will that his resting place should be devoid of structural decorations and that they should commit his body to the mercy of god in an open place" - so possibly a building was build around and keeping the grave open as like Akbar's tomb in Agra, and could be changed to closed roof later.
