The site sits on marshy land where O. Davies once recorded a ‘semicircular bank’ and ‘faint traces of the other half of an enclosure’, though these features have long since vanished from the landscape.

Two separate archaeological investigations, both led by Richard Crumlish, attempted to uncover evidence of these lost structures. The first excavation in November 2005 examined three adjacent sites slated for housing development. Despite digging eight trenches ranging from 10.6 to 60 metres in length, the team found only waterlogged ground; two grass-covered drains crossing the site made parts of the trenches impossible to excavate. Beneath the topsoil lay nothing but sterile natural subsoils of various sandy clays and bedrock, with no artefacts or archaeological features to speak of.

A second investigation in April 2007 focused on another plot within the same archaeological constraint area, this time in an overgrown pasture field. Five machine-excavated trenches revealed a similar story: layers of modern fill containing pottery sherds, concrete and plastic, underlain by undisturbed natural soils. The only human intervention discovered was a modern plastic land drain. Whatever ancient structures once stood here, whether defensive enclosures or underground chambers, have left no physical trace for modern archaeologists to find, remaining only as tantalising references in historical surveys.
