Caz Graham visits the Northumberland countryside to discover stunning art in the landscape, produced by Iranian artist Khosro Adibi.

Khosro is a visual artist from Iran. He's lived in Europe for several years now and has created site-specific environmental sculptures and land art pieces in the landscape.

He has been artist in residence at Tarset in Northumberland since August last year. His work involves carving directly into sandstone, reminiscent of the pre-historic cup and ring marks that can be found in Northumberland.

Caz also meets some archaeologists who spot similarities in Khosro's work to the ancient markings that are found in the area.
