Stonehenge
Welcome to Stonehenge, 2000 BC. This
site has already been a place of worship and learning for the last 1000
years. Let's take a look around at the major features. |
The Sarsen Circle |
The outer sarsen circle consists of 30
uprights, topped by 30 lintels. Each upright weighs up to 25 tons, and each
lintel weighs 7 tons. |
The Trilothons |
5 trilothons are set out in the form of a
horseshoe. They are graded, rising from 6 1/2 to 8 metres
in height. Each of the uprights weighs up to 45 tons. |
The Great
Trilothon |
The Great Trilothon is over 8 metres high. At Winter Solstice, the sun can be seen
setting between its stones. |
The Half-Size
Stone |
One of the sarsen uprights is a Half-Size
Stone. This means that the sarsen circle really
consists of 29 1/2 stones. 29 and a 1/2 is the number of days between
one full moon and the next. Also, viewing from the centre of Stonehenge,
and looking past the Half-Size Stone, the direction is due South, around
which the heavens appear to turn. |
The Bluestones |
There are 2 circles of Bluestones, one
outside the Trilothons, and one within the Trilothons. These Bluestones weigh up to 7 tons each,
and were brought from the Presceli Mountains in Wales by raft and sledge. |
The Altar Stone |
The Altar Stone was placed in the centre of
the site as a focal point for all astronomical observations. |
The Heelstones |
The Heelstones are 2 huge sarsen marker
stones. On midsummer's day, by standing in the
middle of Stonehenge, the sun can be seen rising between them. |
The Aubrey Holes |
The Aubrey Holes around the perimeter are 56
round pits one meter wide and deep, here represented for visibility by round
plinths. |
|
The Sun, Moon and Node Stones are moved
progressively from one Aubrey Hole to another, in order to predict sun and
moon eclipses. |

Station Stone North is the base for many sightlines,
but one of the most spectacular is the Summer Solstice Sunset, viewed from
Stone G. |
