The great landmark that once separated the Roman empire's British citizens from the Celtic tribes of the north will be highlighted, literally, next year by a spectacular art installation as all of Hadrian's Wall is lit up.

The team behind the Northumberland Lights project are to announce plans this week to set up lights along the 73 miles of the wall for three days to draw visitors to the site at night.

'This will be a way of getting people to see the landscape in a different way,' said Zoe Bottrell, director of the Northumberland Lights festival.
