Archaeologists from Historic England spent the day digging test trenches to try and establish the width and depth of the original and subsequent cuttings. We imagined hitting solid chalk within a few inches but this was not the case. The results were not as clear as hoped but seemed to show that the original cut was wide (over a metre) but relatively shallow. A subsequent cut at a later stage was much narrower (less than half the original width) but much deeper. Archive photo’s support this theory…

What a fascinating discovery at Compton Chamberlayne! It reminds me of the time I volunteered on a dig and was surprised by the unexpected layers beneath the surface. The history of our world never ceases to amaze me, especially when archived photos bring the stories to life.

As I read, I couldn’t help but envision the archaeologists’ anticipation of hitting solid chalk, only to be met with unexpected twists in the trench’s dimensions. The contrast between the original cut and the subsequent narrower yet deeper one adds a layer of mystery, leaving me eager to uncover more about the historical secrets beneath the surface. Kudos to the author for shedding light on this intriguing archaeological puzzle.
