This Gurudwara has most historical significance. It is located in Kartarpur and was dedicated to 5th Guru Arjun Dev Ji and 6th Guru Hargobind Ji. Guru Arjun Ji dug up a well to overcome the water scarcity in this place. Also he made a Urn flow up from the well and to fall in River Ganges. This deed eradicated the superstition of not to bath in River Ganges which prevailed among people in those days. So the well was named after River Ganges as Gangsar. Guru Arjun also stated that a dip in this well’s water will rinse all the sins. Guru Hargobind Ji not only preached Sikhism from this Gurudwara but also conducted a battle against Islamic Ruler’s atrocities from this spot.
