Whilst the southern and central henges are open to the public, that is not the case with the privately-owned and wooded northern henge.
Here the trees have been both a blessing and a curse, with road-building destroying its eastern section without any archaeological recording. Yet, parts of this monument- most notably its inner ditch and bank- are well preserved.
As it happens, the northern henge is currently up for sale with a guide price of £200,000. Further details of its sale can be found here: https://www.knightfrank.co.uk/…/west…/hub2306939
