Built in 1764, by Maharaja Ala Singh after his conquest of Sirhind, Qila Mubarak was originally made as a mud fort or kachi garhi. The Darbar Hall has now been converted into a mini museum, which contains rare arms and armours, including the sword and dagger of Guru Gobind Singh and the sword of Nadir Shah, called ‘Shikar Gah’, who invaded India in 1739. This site is under restoration. The restoration work is being undertaken by the Directorate of Cultural Affairs, Archaeology and Museums Govt of Punjab under 13th Finance Commission Projects by Directorate of Cultural Affairs, Archaeology and Museums.
