This area is depicted as showing a system of 4 fish ponds until 1987 when only one is shown as still containing water. The two largest of these ponds were depicted on Jefferys' 1775 mapping of Thrybergh Deer Park. Comparison between Jefferys' map and the first detailed OS plan of Thrybergh Park in the early 1850s shows a re-ordering of the park's arrangement, probably reflecting the growth of aesthetic roles of parkland during this period when most local deer parks were 'landscaped'. This may indicate a medieval origin for these ponds as part of the original deer park. Significant legibility of ponds and earthworks.
