Three Theories About the Stonehenge

In Salzbar Plains, in Wales UK, stands one of the most popular monuments in the world which is the great Stonehenge. Stonehenge dates even before ancient Egypt, The big rocks in the Stonehenge are called the Sursans which weight about 45 tons. People until today don't know the right theory about the use of Stonehenge. There are lots and lots of theories but only three of them come to a purpose. The most popular theory is that Stonehenge was a Astronomical observatory used to to mark midsummer, but research shows that Stonehenge wasn't only visited over the summer it was also visited over the winter when the sun sets between the largest of the central arches. Another theory is that Stonehenge was used as a cemetery where important people were buried, generally Stonehenge was a place for the dead, while Wood-henge was a place for the living. Both of these monuments have channels which connect to the river Avon.And the third theory is that Stonehenge was a landing place for the UFO. I am quite sure that the third theory is false but who knows. Stone henge is also one of the biggest worlds mysteries.
