HAṚAPPĀ (30º-48'N, 72º-52'E), a town in Montgomery (now Sāhīwāl) district of Pakistan, famous for its archaeological finds pertaining to the pre-Aryan Indus Valley civilization, claimed a Sikh shrine commemorating the visit of Gurū Nānak who once stopped here on his way to Multān. Gurdwārā Nānaksar Pātshāhī I, as it was called, came into prominence after the opening of the Gañjī Bār canal colony during the second and third decades of the twentieth century when a polygonal domed sanctum on a high plinth, with a sarovar (bathing tank) and residential blocks near by, was constructed. Special congregations took place on the 1st of each Bikramī month and a largely attended 3-day religious fair was held annually from 1-3 Chet (mid-March). The Gurdwārā had to be abandoned at the time of mass migration caused by the partition of the Punjab in 1947.
