Relevant interests of the site (also see assessment form)
The Pontorson Lane Monolith is a vertical stone of porphyritic dolerite which is incorporated into the external wall of 17th century building called Constantia Cottage. The site was registered as an AS on 18 February 2008. The stone was identified at that time as a prehistoric menhir but it was not known whether it was in situ or whether it had been incorporated into the wall from elsewhere. A protected radius of 5 metres from the stone was therefore initially included within the AS to ensure that the area of archaeological interest was sufficiently encompassed.
The owner subsequently commissioned an archaeological investigation by Dr W Rodwell that concluded the stone is likely to be a re-used prehistoric menhir or a lintel from a dolmen, but was placed here when the cottage was built - the stone perhaps having been a local feature of symbolic importance sufficiently strong to outweigh the awkwardness of re-using it as a building stone.
JH recommendation
Dr Rodwell’s report shows that the prehistoric monolith is not in situ and thereby the area within the 5 metre radius is not archaeologically sensitive. It is therefore recommended that the AS be redefined to apply only to the monolith.
Justification relating to criteria
Registering the Pontorson Lane Monolith as an Archaeological Site (AS) is in accordance with the published criteria for assessment and designation of archaeological sites as set out in Supplementary Planning Guidance Archaeology and Planning which states, “The basis for this registration will be where there exists specific information about the nature and location of archaeological artefacts or remains” including any historic landscape feature or structure which is judged to be of archaeological value.
