The West of Scotland Archaeology Service have carried out an initial investigation at the new Cumbrae Parish Church site, east of the primary school.
The archaeology service revealed that 'buried archaeology has been found', and have requested that further works are required during or before construction.
Speaking to the 'News', Paul Robins, Senior Archaeologist, said: "Two possible features were found during the routine evaluation - one is a possible hearth and the other a possible post hole. Both are laden with charcoal from burning episodes but no artefacts were found within them so their date is unknown at present but as at least one stone tool was also found on the site and because of experience elsewhere, we are working on the basis that these are likely to be of broadly prehistoric date.
"The two features are unlikely to exist in isolation and may well form part of a larger pattern that if uncovered could give us clues as to function and date. Given that one is a hearth and one a posthole it would appear to be domestic activity and it maybe at the end of the day that a house would be uncovered consisting of a ring of postholes supporting a roof around a central fire, but at present no-one knows.
"Further archaeological works are required during the initial topsoil stripping of the site ahead of development in order to achieve the required investigations. This will be controlled and monitored by archaeologists with a view to uncovering any related remains that exist within the application area."
