Gurudwara Ber Sahib is a popular religious site for Sikhs that is located in Sultanpur Lodhi. It is believed that Guru Nanak Dev Ji - the first Sikh guru - spent 14 years of his life here. He also attained enlightenment at this place, when he was bathing in the small rivulet called Bein.
The place has been named after the Ber Tree planted by the Sikh guru. The current structure was built by Maharaja Jagatjit Singh on a high plinth with various octagonal columns and an ornate entrance gallery. Multiple floral designs adorn the walls and ceiling of this structure. A fair is organised in November every year to commemorate the birth anniversary of Guru Nanak Dev Ji.
