Some of Iraq's most significant archaeological discoveries have been made in the city of Samara.

Samara lies on both sides of the River Tigris north of Baghdad. It marks the site of a powerful Islamic capital that ruled over the Abbasid Empire which stretched from Tunisia to Central Asia for a century.

It’s estimated 80 per cent of it still lies undiscovered.

UNESCO says it should be protected as a World Heritage Site.

But locals say some of its landmarks are being left to crumble.
