Gurdwara Kartarpur Sahib commemorates the town of Kartarpur founded by Guru Arjan Dev, the fifth Sikh Guru who completed the construction of the Harmandir Sahib and compiled the Adi Granth. A historic sandalwood post (Tham) stands inside the Gurdwara where Guru Arjan Dev struck it into the ground declaring, "This shall be the support of our faith." The Guru also had a well dug here for the local community, and it remains a place of pilgrimage for Sikhs honoring his enduring legacy.
