The Walls of Derry and the ancient town of Pompeii are to be digitally scanned as part of a major European 3D project.
The mile-long walls – the largest scheduled ancient monument in Northern Ireland – are being scanned for their 400th birthday.
The work is being carried out as part of the 3D-ICONS Project, which involves 16 teams working across 11 different countries.
As well as Londonderry's 17th century City Walls, also getting the 3D treatment are Pompeii in Italy and the Newgrange neolithic site in the Republic.
The work is being undertaken by the Discovery Programme in Dublin – the Irish partner in the 3D-ICONS project.
Mark Lusby, City Walls heritage project co-ordinator with the Holywell Trust, said: "We will be showcasing at the Walls 400! History Conference next Saturday and Sunday some of the early results obtained so far.
"We are working with Digital Derry and the Nerve Centre Fab Lab to look at how the data generated can be used for our heritage education programmes and to help entrepreneurs develop new commercial products.
"The fact that Derry's Walls have been selected is testimony to how their heritage value is perceived at a national and European level. The data produced will be of use for gaming, TV and films, as well as for providing 3D models and fly-throughs for exhibitions and websites."
Tickets for the Walls 400! History Conference can be purchased from the Playhouse on 028 7126 8027. Its programme can be downloaded at www.walls400.com.
