Stonehenge is Britain’s greatest national icon, symbolizing mystery, power and endurance. Its original purpose is unclear to us, but some have speculated that it was a temple made for the worship of ancient earth deities. It has been called an astronomical observatory for marking significant events on the prehistoric calendar. Others claim that it was a sacred site for the burial of high-ranking citizens from the societies of long ago.

This ancient monument of huge stones solitarily standing on the Salisbury Plain in Wiltshire, England has captured imaginations for centuries. Theories about who built it have included the Druids, Greeks, Phoenicians, and Atlanteans. Speculation on the reason it was built range from human sacrifice to astronomy.

Investigations over the last 100 years have revealed that Stonehenge was built in several stages from 2800 - 1800 BC. It seems to have been designed to allow for observation of astronomical phenomena - summer and winter solstices, eclipses, and more.

The Trilithons are ten upright stones arranged as five freestanding pairs each with a single horizontal lintel. They were erected within the Sarsen Circle in the form of a horseshoe with the open side facing north-east towards the main entrance of the monument. They were arranged symmetrically and graded in height; the tallest is in the central position. Only three of the five Trilithons are now complete with their lintels. The other two both have only one standing stone with the second stone and lintel lying on the ground.
