A patchwork of medium sized fields of irregular shape which are indicative of piecemeal enclosure. Although some boundaries have been lost since the 1st edition OS map of 1854, the fields are not huge and the essential character remains. The eastern boundary of the polygon probably formed the outer boundary of the deer park. Significant amounts of medieval pottery, including wasters have been found in the fields surrounding Firsby Hall farm. Legibility is uncertain as there is currently no evidence as to the nature of the previous character type.
