A high view along the gallery axis from the
WSW.
Two low jamb stones can be seen standing in the foreground, just inside
the line of the gallery walls.
This is the presumed original entrance to the gallery, but we are a bit doubtful
about this as the surviving
outer walls diverge by at least 1.5m towards the rear of this photo, and the
southern outer wall projects
more than a metre past the gallery "entrance jambs".
