But Was it 18' or 18" Tall?

Whilst doing my morning reading, I come across the fact that archaeologists in England are doing a dig inside the confines of Stonehenge - for the first time in almost 50 years. The first thing that made me think of was this:

In ancient times, hundreds of years before the dawn of history. There lived a strange race of people...the Druids. No one knows who they were, or what they were doing... but their legacy remains... hewn into the living rock of Stonehenge...

Anyway, after that, I went to the BBC site, to read all about the dig. Complete with video for each day, and an awesome interactive panorama.

Cool stuff. UPDATE: The BBC link is dead, but here's a good replacement.
