L19 - the guardian stone of Newgrange

This is stone L19 (left-hand orthostat number #19, counted as you walk up the passage from the entrance. Most visitors to Newgrange never see this stone. It is positioned at part of the passage that is quite tight, and many people turn their bodies sideways (and, in many cases AWAY from this stone) to squeeze between the orthostats. Thus, they miss one of the most beautiful stones from the interior of the Newgrange monument.

Some say that these symbols represent a face, like a guardian of the monument, watching all those who enter and exit the ancient interior.
