Lockdown Archaeology: a walk in the woods

By Rob Evershed, Project Officer (Geophysics)

Due to the ongoing coronavirus situation I’ve found myself confined for the majority of my time to my home. I’m fortunate in so much as I can continue working on writing up various projects, but it’s still a little claustrophobic, a feeling I imagine a lot of people are having at the moment. So my daily escapism comes in the form of walking my dog just after 4pm. I’m lucky to have some woods just up the road where I can easily go, and where I have turned my archaeological eye on.

The woods are part of a landscape of managed woodland in the area, although parts of it are slowly returning back to nature as at the moment there appears to be limited removal and replanting of trees. I’ve always been interested in the slightly unusual lumps and bumps within the wood, but never got any further than thinking it might be interesting to try and work out what might be going on.

Well finally with the lockdown I got round to doing a bit of detective work. The Environment Agency has Lidar data they provide for free on their website, and this proved perfect for getting a better look at what might be going on.

As you can see from the image, the area available for dog walking has a number of lumps and bumps, including a sub-circular swamp area extending from the southern edge. It does continue further to the south, but that’s private woodland.

However the most interesting feature I’ve noticed is the strange square feature towards the northeast corner of the area. Here’s a zoomed in Lidar image.

Exploring the area this feature has fairly clear banks surrounding a lower flattened area that sloped gently to the west. Without all the trees and vegetation it would undoubtedly stand out very clearly as a distinct feature, but with the trees and vegetation it is actually very difficult to see. Taking good photos of earthworks is notoriously difficult, and being in the woods makes it even trickier. However here are a few shots from which you might be able to make out some of the banks.

From it’s square shape, and distinct ninety degree angles, it definitely looks like a manmade feature. The surface geology is sand and gravel, but the woods in this area definitely pre-date the twentieth century as they are present on the 1st Edition OS map. Nearby heritage features include a deer park, a deserted medieval settlement, and the site of a former priory. But apart from the woodland potentially being used for one or all of these places, I’m at a bit of a loss for what the square feature might be, or why it was created. Currently my imagination is suggesting it’s an Iron Age fort, but I have no evidence to back that up. What do you think?
