Gurdwara Sis Ganj Sahib is built at the site in the Chandni Chowk area of Old Delhi, where the revered ninth Sikh Guru, Guru Tegh Bahadur was beheaded, on Wednesday, November 24, 1675, on the orders of the Mughal emperor Aurangzeb for refusing to convert to Islam. Before his body could be quartered and exposed to public view, it was stolen under the cover of darkness by one of his disciples, Lakhi Shah Vanjara, who then set his home alight to cremate the Guru’s body.
The ‘Sis’ (severed head) of Guru Tegh Bahadur was taken to Anandpur Sahib by Bhai Jaita, another devotee of the Guru where it was cremated by the Guru’s young son, Guru Gobind Rai.
Bhai Jaita who had been of the Majhabi (scavenger) caste, was renamed Bhai Jivan Singh on the day that Guru Gobind Rai created the Khalsa and added the names Singh or Kaur to the names of Sikhs. Bhai Jivan Singh was one of the Martyrs at Chamkaur. Guru Gobind Singh was the tenth and last living Guru of the Sikhs.
The present builcling was raised in 1930. The trunk of the tree under which the execution took place is preserved behind a glass screen.
Adjoining the Gurdwara Sis Ganj is the Kotwali (police station), where the faithful disciples of the Great Guru Bhai Mati Das, Bhai Dyala and Bhai Sati Das were tortured to death at about the same time.
