This is situated on the site of a medieval priory. In common with a lot of Scottish cemeteries with graves dating from the 18th century, the stones have figures of skull and crossbones, hourglasses and shovels. A monk at Pluscarden Abbey told me this was because they were a pretty morbid lot around that time - the skull and crossbones signified the person was dead, shovels and spades represented the digging of the grave, and the hourglass was a reminder that your time will come!
