More than 130 3D images of ancient monuments and buildings have been created to bring to life some of the country’s most important heritage sites.
The models of places as significant as the passage tomb at Newgrange and the monastery at Skellig Michael are so detailed they make it easier to view engravings and other features which may be missed by the naked eye.
Other symbolic sites include the Hill of Tara, Derry City Walls, the Poulnabrone dolmen, Glendalough, Clonmacnoise, high crosses and the intriguing Boa Figure.
Heather Humphreys, Minister for Arts, Heritage and the Gaeltacht, said the data would benefit education, tourism and conservation work.
She said: “How many of us have been inside the passage tomb at Newgrange, or have scaled the heights of Sceilg Mhichil?
“This fascinating website will give members of the public a much closer look at many of our best known heritage sites.
“We have such an incredible array of ancient monuments in this country; this website effectively brings them right into your home.”
The 3D scans will be hosted on a new website 3dicons.ie where users can access images, a video, 3D models, a location map and information on its historical and archaeological significance.
It is part of a European project to bring together heritage sites on one portal.
