Phil Harding tells the Time Team podcast about a remarkable discovery at a site just five kilometres from Stonehenge. Holes thought to have once contained huge wooden posts were discovered which date back 500 years before the stones at Stonehenge were erected. The posts at Bulford line up with the summer and winter solstices, in the same way they do at Stonehenge. It means this new discovery could have been an early prototype for the solar alignment seen at Stonehenge.

You'll hear Phil talking to Helen Geake and Martyn Williams, alongside Fabio Silva, an astroarchaeologist, who helped to confirm the findings. There are also details of how you can contribute to Time Team's future research by suggesting sites for new digs.
