The Stones of Stonehenge
A site with a page devoted to each stone at Stonehenge
This is the tallest standing stone at Stonehenge. So tall, in fact, that it's hard to get a clear single photo of the NE face so here are three separate photos.
Graffiti on the SW lower face:
The light and dark pattern on the NW lower face that some people see as an alien "Grey".
Estimated above ground weight: 23.06 tons
