Monument record MBC48678 - Subrectangular pond, close to the River Thame, Nether Winchendon

A subrectangular pond of probable medieval/post medieval date is visible on historic aerial photographs and remote sensing data as extant earthworks and was mapped as part of the Aylesbury Vale Aerial Investigation and Mapping project (EBC18604). Located approximately 360m south of Mainshill Farm, Nether Winchendon, and centred at SP 74479 12279. This pond is visible as subrectangular ditch measuring approximately 65x32m with an external bank and internal platform with a hollow at the centre. The external bank measures approximately 85x47m and the ban around the central platform measures 47x12m. A very similar feature was also mapped approximately 620m to the east, also close to the river. It is not clear where the water supply would have been, but is may have been at the north eastern corner. It is possible that what appears to be a road from the north could have been a water channel but this runs from the top of a limestone hill, against the direction trend of the geology which usually dips towards the south east. Other similar features have been recorded as fishponds. (1-2)
