To commemorate the launching of an international campaign for the safeguarding of Moenjodaro, UNESCO struck one of its first world heritage medals in 1974. The ruins of this huge city, built entirely of unbaked brick in the third millennium BC, lie in Pakistan’s Indus Valley. It provides an astonishing example of modern town planning, with streets crossing at right angles, multi-storey houses and an underground sewage network. At the time of the campaign these remains were threatened with flooding from the Indus River and encroaching salinity.
Moenjodaro was inscribed on the World Heritage List in 1980. The campaign was completed in 1997, giving way to a master plan to ensure the sustainability of the conservation work. The medal’s obverse features a king-priest, while the reverse has a pictographic inscription of a unicorn from a seal found at the site.
