Stonehenge
I guess most of us have heard Stonehenge of Great Britain, if you don't know yet what they are then, first of all check basics about them by clicking here.

Now, Second Phase included movement of stones again but it was conducted around 2000 BC when some more stones were brought in from 25 miles.
Now, again third Phase was really amazing which included re-arranging of all those stones, i dont know somehow someone felt that these stones re-arranged to be moved and only God Knows how they did it. The mystery is how where they able to move such massive stones ,, each weighing in tonnes. Legends describe some Giants Moving it and carrying it, but do Giants Exist?? If Giant Men can exist then Fairies can also exist .... :P
No one knows why these things were created and what was there purpose, but one thing is for sure, these Stones hide a secret which is yet to be known to mankind. For info how they were created check wiki page link i gave above..
