An archaeologist in Ireland has discovered an ancient megalithic tomb — one that was seen and sketched in the 19th century but then lost for almost 200 years.
Local scholar Billy Mag Fhloinn, an archaeologist and folklorist with Sacred Heart University in the Irish town of Dingle, found the tomb with the help of photogrammetry, a technique in which photographs are digitally pieced together to create a virtual 3D model that can be rotated and examined in detail.
