According to local tradition, supported by an old handwritten document preserved in the Gurudwara, one Bhag Ram, a jhivar of Lehal, waited upon ninth guru of Sikhs Guru Tegh Bahadur during his sojourn at Saifabad (now Bahadurgarh), and made the request that he might be pleased to visit and bless his village so that its inhabitants could be rid of a serious and mysterious sickness which had been their bane for a long time.

Raja Amar Singh of Patiala (1748–82) had a garden laid out on the site as a memorial which he entrusted to Nihang Sikhs.

In 1920, during a survey for the proposed construction of Sirhind-Patiala-Jakhal railway line, it appeared that the banyan tree under which had sat Guru Tegh Bahadur would have to be removed.

It was later transferred to the Dharam Arth Board of the Patiala and East Punjab States Union and eventually to the Shiromani Gurudwara Prabandhak Committee.

On the left of the pathway leading to the principal building is a small marble shrine marking the site where Guru Teg Bahadur had sat under the banyan tree.

The pinnacled lotus dome on top has a round sun-window on each side with a curved coping, projected horizontally at the ends.
