Sounds like a great spot for a special pre-Christmas caroling event. Ideally with male and female students sitting on top of the “chest high wall”, straddling it, and arranging themselves in an alternating male-female line. Afterwards, on the solstice, turn it over to the Wiccans, who will dismantle the wall, make a bonfire out of the remnants (using the nearby piles of pamphlets as kindling, of course), and dance around it.
