Work has begun to digitally document the Antonine Wall as part of an innovative project using new technology.

Heritage experts from the Scottish Ten project are using laser scanners on areas of the wall near Bonnybridge, Falkirk to produce a detailed survey of the site.

While it took the Roman army 12 years to complete the wall in the second century, which stretches for 40 Roman miles (60km) between Bo'ness and Old Kilpatrick, it will take the experts two weeks to scan the Rough Castle and Bar Hill sites.

The survey is the latest to be carried out by the Scottish Ten project, which is documenting Scotland's five World Heritage Sites and five international heritage sites.

It is a joint initiative by survey specialists at Historic Scotland, experts in 3D visualisation from Glasgow School of Art's Digital Design Studio and international non-profit organisation CyArk.

The measurements gathered can be used to improve management, conservation and interpretation of these sites while also providing an educational tool for future generations to learn about them.

Realistic reconstructions of the sites could be generated from the data.

Dr Lyn Wilson, the project manager, said: "The Scottish Ten project offers the exciting possibility of virtual reconstruction, based on accurate survey information, to help in-site interpretation.

"We are also using these surveys as a training exercise for Historic Scotland's architectural technicians to build capacity within our organisation to better enable us to fulfil our commitment to digitally document in 3D all 345 properties in the care of Scottish ministers."

The international sites covered by the project are the Eastern Qing Tombs in China, Mount Rushmore in the US, Rani ki Vav in India and Sydney Opera House in Australia, with the fifth international site still to be announced.
