Stonehenge
On the longest day of the year, the June
21st summer solstice, the rising sun appears behind the
'Heel Stone' - one of the main stones, creating the
illusion that it is balancing on the
stone.
No one really knows what the creators of this monument had in
mind when, over the course of three renovations spanning 1500
years, they built this famous ring of stones on a wind-swept
hill.
Location: Salisbury, England
Latitude, 51d 4' North
Longitude, 1d 48' West
Construction: This famous megalithic
structure was apparently built in three stages beginning around
2950 B.C. and extending to 1600 B.C. During the first period of
construction, it was a circular enclosure with two earthen
banks and a ditch. During the second construction phase, about
2,000 BC, the inner circle of small bluestones, was set up, but
abandoned before completion. The stones used in that first
circle are believed to be from the Prescelly Mountains, located
roughly 240 miles away, The bluestones weigh up to 4 tons each
and about 80 stones were used, in all. Around 1600 BC, the
outer ring of giant Sarsen Stones (as much as 50 tons each)
were transported from the Marlborough Downs 20 miles to the
north. It was originally thought that Stonehenge was built by
ancient Druids, but this idea has been replaced by the idea
that the late-Neolithic Becker People were probably the
builders. Ancient Druids worshiped in forest temples and,
presumably, had no need of stone constructions, according to
some archeologists.
Alignments: On the longest day of the year,
the June 21st summer solstice, the rising sun appears behind
the 'Heel Stone' - one of the main stones, creating the
illusion that it is balancing on the stone. The Heel Stone sits
along a wide lane called the Avenue. The rising Sun creeps up
the length of the rock, creating a shadow that extends deep
into the heart of five pairs of sarsen stone trilithons -- two
pillar stones with one laid across the top -- in the shape of a
horseshoe that opens up towards the rising sun.
Archeoastronomers have also identified other stellar alignments
with some of the other stones, however some controversy remains
as to whether these stellar alignments were intended, or merely
accidental.
