Antechamber roof structure viewed from main
chamber through portal stones.
The inner passage and antechamber are roofed with six lower lintels, all are
visible in this photo rising like the underside of a staircase.
There are another two lintels set above the lower ones, presumably to relieve
stress, one of these is visible centre shot above the thick fourth
lintel directly above the antechamber portal stones.
