This cupmarked stone has
been used in the construction of the northern side chamber,
it bears 24 cups but they were originally buried in the dry stone walling here,
the alcove
we see above is modern. This stone was obviously part of an earlier
megalithic structure
which has been re-used in the construction of the passage grave. The
carvings had no
significance to the new monument and the stone was used simply as a structural
element.
