Newton henge is a prehistoric henge monument in Wales, identified as a cropmark and protected by Cadw under reference GM580. The site sits on Dinantian bedrock, a formation of limestone with subordinate sandstone and argillaceous rocks that dates to the Mississippian period. This underlying geology would have influenced both the construction and visibility of the monument across the landscape.
Henges typically date to the Neolithic and Bronze Age, comprising a circular or oval earthwork defined by an outer bank and inner ditch. The cropmark evidence at Newton henge—where buried features create differential crop growth patterns—reveals the monument's layout where surface topography may obscure it. The local limestone geology and mixed sedimentary bedrock would have affected how water drained through and around the ditch, shaping the monument's long-term preservation.
The site's survival as a cropmark rather than prominent earthwork suggests significant erosion or levelling over millennia. Its protection by Cadw recognises its importance as a record of prehistoric ceremonial practice in Wales. Newton henge contributes to understanding the distribution and form of henges across the landscape, particularly in regions where geological conditions favour their survival as subsurface archaeological features rather than visible earthworks.
