Durrington Dig 2016 – Thursday 4 August

Progress is being made on what is turning out to be a fascinating narrative here at Durrington Walls Henge. The two pits the site team uncovered at the beginning of the dig gave off very different signals in the geophysics and, as it turns out, have conceivably been dug for very different reasons.

So what were these pits for? The answer is curiously complicated.


This pit/ramp gave off a strong, well-defined signal in the geophysics. Here it has been half-sectioned, with a ramp leading down to the pit, perhaps originally dug to guide in a timber post.

The pit in the photo above has led the team to ask, ‘was a post ever erected here?’ The archaeology had so far indicated two main theories:

  • one is that the pit and ramp were dug, a timber post was intended but never erected in the pit, and the henge bank of Durrington Walls was constructed over the pit as it was left, or
  • the pit and ramp were dug, a timber post was erected, then removed, then the henge bank was constructed over the top.

The team needs to continue working on this feature to see if the form of the ramp at the pit edge is sharp or crushed (by a timber post), if there is any packing material and if the base of the pit has a ‘kick back’ as the post was removed. Only then might we be able to see if the intended post was ever put up.

The other pit tells a different story.


Again, further work needs to be done, but one theory is that this pit (photo above) may have contained a post that decayed in situ. When this happened, material fell into the void and formed what is known in archaeology as a post pipe. Normally this material would be soil, but because the henge bank was constructed over the pits, it is possible that the bank material has formed the post pipe.

There is a lot more that this pit can tell us – possibly even about the construction process of Durrington Walls henge. More on that intriguing theory later in the blog.

Stonehenge Hidden Landscapes – What does it mean?

More news  on the significance of the Stonehenge Hidden Landscapes Project’s discoveries in the interview I did with Good Evening Wales yesterday (at 52 minutes 30 seconds) http://www.bbc.co.uk/programmes/b04g40rr


Over the course of the last few years two different teams have at different times been revealing the secrets of the Stonehenge Landscape by using cutting edge extensive geophysical survey  techniques. You can find out more about their work and those that came before them by taking a peek at this article that I wrote in the National Trust’s ABC magazine in May 2012  . You’ll find it on page 12.

Happy reading…
