A small building, partially embedded in the wall of a warehouse at 49 Moonstone Lane, has for decades housed the grave of a Muslim woman named Syarifah Zainah Alhabshi, according to a government record. The authorities had initially slated the pre-World War II grave for exhumation, based on an on-site notice from March 9.

The exhumation was planned as part of the handover of the land, near Kallang River, from a government agency to the state. But exhumation plans have been put on hold after members of the heritage community dug around to find out the significance of the grave.
