This Gurdwara is situated 16 Km Northwest of Jalandhar City in Kartarpur town and is in the Memory of Fifth Sikh Guru, Shri Guru Arjun Dev Ji and Sixth Sikh Guru, Shri Guru Hargobind Sahib Ji.    Guru Arjun Dev Ji developed this town. Due to shortage of water Guru Ji got a well dug up in 1599. Guru Ji got extracted a Gadva (a small Utensil) of Bhai Visakhi Ram from this well, which had fallen into River Ganges. Guru Ji got cleared the superstition of bathing at River Ganges from People's mind. Hence, the well and the Gurdwara were named as Gangsar. Guru Ji blessed this well by saying:   "Sakar Gang Yeh Naam Dharayo, Ganga Te Hum Adhik Likhayo  Jo Banchha Kar Ethe Awe, Man Banchhat Var Sak Hi Pave "   Meaning I have named this well as Gangsar which will give same benefits of bathing at River Ganges. Whosoever will come here with a wish, his wish would be fulfilled.   Guru Ji said," whosoever will take bath here with pure heart , all his physical and mental sufferings would come to an end".   A Place near the well has been named as 'Shri Manji Sahib'. At this place Guru Ji used to arrange preaching Diwans.   Guru Hargobind Sahib Ji also used to preach his followers at this place. Guru Ji fought his Fourth Battle against Mughal atrocities in 1635 at this place and got victory. Guru Ji killed his former Jarnail Painde Khan (who had left Guru Ji and joined Mughals) at this place. Guru Sahib took off his Kamarkassa (a waist pad or belt) and took rest at this very place.
