More holes drilled into the NE side of the
roofstone.
These holes still have the plugging used to anchor the plaque, or notice that
was once
attached here, and most probably on the west side of the stone as well.
Attitudes to the preservation of ancient sites have changed over the years, and
this
kind of defacement was once considered acceptable.
It seems that installers were not too good at their job, although the holes here
are smaller
than those at the west, they have had to drill some of them twice.
