The survey identified one feature considered to have medium potential based on this analysis.

This feature consists of two sharply defined strong positive anomalies that form two rectangles, one 7.6 / 5.4m and the second 12.5 / 7.2m. Their rectangular form and size indicate something constructed and therefore could be associated with a building predating the 19th century historic OS mapping.

This feature is detected running parallel with Retford Road. There is a possibility that these structures may be associated with the modern use of the site as a recreation ground, however, the size and rectangular form indicate a potential for them to predate the historic Ordnance Survey mapping of Mattersey. It is therefore recommended that further investigation be undertaken to determine the nature of these anomlalies.
