Indian Punjab's Muslim population fell from a majority in the undivided province to under two per cent, concentrated at Malerkotla. The buildings did not leave.
Some were destroyed. Some were converted to other uses, as houses, stores and in a number of cases gurdwaras or temples. Some were maintained by local Sikh and Hindu villagers who kept the lamp lit at a pir's grave without regard to whose grave it was.
The shrine of Haider Sheikh at Malerkotla, Rauza Sharif at Sirhind, the Roshni mela shrine at Jagraon, the shrine at Chhapar, and hundreds of small field mazars are the surviving thread.
The Waqf Board holds title to a substantial amount of property in Punjab and a large proportion of it is occupied or disputed.
The same happened in reverse in Pakistani Punjab to gurdwaras and mandirs, and neither state has surveyed what survives.
A field shrine kept up for eighty years by people of another religion, whose own community left in a year, is one of the more human things in this region's record and there is no list of them.
Several hundred mosques, tombs and shrines survive in Indian Punjab, most of them without a congregation, and their condition ranges from maintained to demolished.
The ones that survived intact usually did so because a village took them on: Guru ki Maseet at Sri Hargobindpur, the mosque at Hedon Bet, the small maris kept by Hindu and Sikh families.
The waqf board holds title to most of the rest and possession of very few. The buildings are a physical record of a population that is not in the district's account of itself.
