Barood Khana of Lahore Fort, which literally means an arsenal depot, was built during the British rule. This building was built in 1857 during British era, for the purpose of storing gun powder. In this depot, the British had been storing the gun powder as well as all kinds of arsenal. According to historic map of Lahore Fort, it was found that there existed a garden with arcades around it, before the construction of Barood Khana. The structure was the part of Alamgiri Gate and Musammam Darwaza of Lahore Fort and later during the British era a road was constructed in between to connect the Hathi Gate with Diwan-e-Aam. Before this road it was a garden complex and this same road is used today to enter the Lahore Fort.
The entire structure of the Barood Khana was suffering from severe threat and damages and the building also had bulging plaster, misplaced or dismantled brick masonry, missing cornices, damaged wooden doors and ventilators, blackish surface and graffiti inside the building.
The doors and windows were seen totally injured because of aging factor, termites and especially because not enough attention was paid in the past.
Walled City of Lahore Authority (WCLA) has done conservation of this building, with the cleaning of the structure and removing tons of debris and wild plantation followed by the documentation process. This building was restored in 2019
