Part 4: Stonehenge
Paul's last postcard from the UK comes from Stonehenge, where he introduces a new theory on just what these huge ancient monuments were for. In the same way you might tie a ribbon around your finger to remind you to pick up milk on the way home, these monuments were memory signals to the people who built them.
In this 4-part postcard series around the UK, our director Dr Paul Willis visits 4 different places of scientific interest: British Museum of Natural History, Royal Institution of Great Britain, London's Roman Wall, and Stonehenge.
