Upper chamber viewed from the east cell.
The western "cell" is centre shot here, it is the largest space in the upper
chamber measuring 2.0 x 2.8m. Two of the vertical slabs set into the
chamber walls can be seen either side of the ranging pole (1m) and the top of
the third can just be seen above the east cell portal stone on the
far right. The top of the ladder used to access the lower chamber can be seen
emerging from the hole in the broken central lintel.
