The Four Stations or **Station Stones** stand inside the bank more
or less on the Aubrey Hole circle. Two, diagonally
opposite, have mounds and ditches, the other two do not.
These mounds/ditches overlay both Aubrey
Holes and the bank.

The Station Stones form a rectangle whose diagonals intersect at 45°,
very close to the centre of Stonehenge
The
sides and diagonals of this rectangle possess what Gerald Hawkins
called 'astronomic significance.'
One pair of sides mark the Summer Solstice Sunrise/ Winter
Solstice Sunset, the other pair indicate the most northerly/southerly
moonrise/moonset.

Only at, or very close to, the latitude of Stonehenge ( 51' 10" )
do these alignments intersect at an angle of 90°.

*'The implications of this are that the
builders of Stonehenge had a knowledge of the global nature of the
Earth' - Devereux*

As the diagonal view across the 'Four Stations' is blocked by the
central Sarsen stones, it is likely that the central Sarsen circle came
after the Station stones in the sequence of construction.
