There's a vote taking place on the BBC web site to nominate the "Seven Man Made [sic] Wonders" of the south west of England. You may like to nominate a site of your choice:

Obviously, if you're aim is to boost the chances of a prehistoric site getting into the top 7 it would make sense to choose an obvious one (not that I'm trying to influence the voting here).
