Original passage entrance area.
The two vertical edges seen in the foreground of the photo above mark the original extent of the passage, A slight "step", most noticeable
on the southern (right) wall, marks the height of the roofing stones. Farrer found the passage covered over its whole length with edge-set lintels (2),
although these had been removed from the outer passage by the time of Childe's re-excavation (4) and remain absent today.
The gaps either side of the entrance have been left to illustrate the cairn structure here, note how the bottom courses of the whole cairn are
well below the level of the external platform (grass level), necessitating the provision of steps for modern access.
