The Garioch was given to David, Earl of Huntingdon (1144-1219), the grandson of David and brother of Malcolm IV and William the Lion, who built a fortress on a high mound, known as a Bass , surrounded by a wall erected on a lower mound.

The reconstituted stone is carved with a crescent, broken lines in a V and Z shape and a snake. On the lower part of one of the two sides is a script in Ogham, the writing used in the times of the Celts.
