Pakistani officials say they are doing their best to save one of the most important archaeological sites in south Asia, Mohenjo Daro. But some experts fear the Bronze Age site could be lost unless radical steps are taken.
It is awe-inspiring to walk through a home built 4,500 years ago.
Especially one still very much recognisable as a house today, with front and back entrances, interconnecting rooms, neat fired brick walls - even a basic toilet and sewage outlet.
Astonishingly, given its age, the home in question was also built on two storeys.
But it is even more impressive to walk outside into a real Bronze Age street, and see all of the other homes lining it.
