Comet Stone, Stenness Standing around 140 metres to the south-
east of the Ring o' Brodgar is the monolith now known as the
Comet Stone. Standing 1.75 metres high (5ft 9in), the Comet
Stone is on a low, oval platform around 14 metres (45ft) in
diameter. The monolith appears to have once been part of a
group, the only surviving evidence of which are the stumps of
two broken stones. Whether these stumps represent the remains
standing stones or actually formed a structure of some sort is
unclear. It has been suggested that the Comet Stone was once
part of a table-like "dolmen" construction, similar to the one
once thought to stand in the centre of the Standing Stones o'
Stenness. The stone's position in relation to the Ring o'
Brodgar's south-eastern entrance hints that it had a part to
play in a hypothetical ceremonial procession way between the
Brodgar ring and the Standing Stones o' It is also marks a
superb vantage point for viewing the entire Brodgar ring and the
expanse of landscape and sky surrounding it.
