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, Stirlingshire, to produce a detailed survey of the site.
It will take the experts two weeks to scan the Rough Castle and Bar Hill sites, along the length of the wall from Bo’ness to Old Kilpatrick.
The survey is the latest be carried out by the Scottish Ten project, which is documenting Scotland’s five World Heritage Sites and five international heritage sites.
Project manager Dr Lyn Wilson 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.”
