Stonehenge in Wiltshire, in the Salisbury Plain of England, is believed to be constructed from 3000 BC to 2000 BC. Stonehenge is traditionally accepted as a ceremonial and ritual site of the Neoliths. In the past century purpose of Stonehenge has took on astronomical significances. Many believe the Stonehenge was used as a kind of calendar, recording the Sun and Moon’s orbits about the Earth, as they would’ve have appeared to prehistoric man.
The famous of these significance is the midsummer alignment, the one where the sun is most frequently photographed rising above the Heel Stone. If an observer is standing inside the stone circle facing north-east, he would be able to see the Sun rise exactly above the Heel Stone.
There are also proposed lunar alignments as well. The four station stones form a rectangle. The short sides of the rectangle point towards the midsummer sunrise and midwinter sunset. The long sides face the most southerly rising of the moon, if viewed towards the south-east direction.
It is also widely accepted that Stonehenge was used to predict eclipses.
