Among these is a stone cross, or rather what remains of one, now kept in the Stone Store at the visitor centre rather than standing in open ground where a casual visitor might stumble upon it.

The piece is the lower portion of what was once a complete free-standing cross. Harold Leask, who documented Glendalough's national monuments in his 1950 publication for the Stationery Office, recorded it carefully: the surviving section is just under two centimetres thick and formed part of a design in which a tapering shaft rose to support arms that flared outward towards their ends, a form sometimes called a ringed or expanded-arm cross typical of early medieval Irish stonework. At only four centimetres in thickness, it is a relatively slight piece, suggesting a cross that was elegant rather than massive. Leask's measured drawing remains a useful record of what the full form likely looked like before it was reduced to this fragment.
