Another attempt is to be made next year to solve the mystery of how the largest stones used to build Stonehenge were moved reports BBC News Witshire
In 1996, a BBC TV programme aimed to find out how the stones for the largest trilithon were put into place, and how the lintel was placed on top.

Archaeologist Julian Richards is teaming up with farmer Tim Daw to see if modern techniques are any more efficient.
