The place where Bhai Mani Singh was martyred is situated inside the Masti Gate which is behind the Lahore Fort. Bhai Mani Singh was born in a pious and dedicated Gursikh faimly which was Devoted to the Gurus. Bhai Mani Singh had the rare privilege to be a child mate of Guru Gobind Singh. Bhai Sahib had also the honour to scribe the holy Sri Guru Granth Sahib in the presence of Saheb-i-Kamal Sri Guru Gobind Singh Ji. In A.D. 1721, Mata Sundri Ji appointed Bhai Mani Singh as a Granthi of Sri Harimandir Sahib. Bhai Mani Singh, with the permission of the Goverment, on the occassion of Diwali, invited the Sikhs to Assemble at Sri Harimandir Sahib but when Bhai Sahib came to know that the authorities conspired to kill the assembled Sikhs, he postponed the congregation. For this offence, Bhai Mani Singh was imprisoned. Earlier he was enticed and afterwards threatened with dire consequences but Bhai Sahib did not yield to them and remained steadfast and firm. At the place in A.D. 1724, Bhai Mani Singh was martyred by cutting limb by limb. There was also an old well at this place where after bieng martyred, the Sikhs were thrown into. At first the management was with the Mahants. In 1923, the local committee took over the management which was transferred to S.G.P.C. from 1927 to 1947 A.D. After partition, this place was locked up and is still so.
