CHITTAGONG (22Â° 21`N, 91Â° 50`E), a major port town of Bangladesh, situated on the right bank of Karnaphuli River, 20 km from its mouth, has a historic Sikh shrine, called Gurdwara Sikh Temple, dedicated to Guru Nanak, who is believed to have stayed here briefly in 1507-08. Local tradition connects this Gurdwara with the story of the conversion by Guru Nanak of Bhai Jhanda Badhi, Raja Sudhar Sen and his nephew, Indra Sen. The story occurs briefly in the B40 Janamsakhi and at some length in the Bala Janam Sakhi. Gurdwara Sikh Temple is situated in the middle of Chowk Bazar. An old well adjoining it is still in use.
