Although the correct evening sunlight conditions are required to see traces of these 5 cup marks, they can be found on the inside of the smaller, left hand stone that forms part of the entrance to the chambers from the fore-court, of the Cashtal Yn Ard Chambered Cairn. There appear to be 4 in an arc with another in the centre of this group roughly forming the point of the arcs radius. Photographed during an Archaeology Safari on the Isle of Man 1st May 2004.
