Monks Pond - Belchamp Walter - a.k.a. The Long Pond
Monks Pond in Belchamp Walter is also known as "the Canal".
The archaeologydataservice website say that the earthworks are situated to the East of St.Mary's Church Belchamp Walter. I would say that it is more like between East by North and East North East of the Church.

The 1897 OS map shows the earthworks as part of the drainage system
The Description (on the archaeologydataservice website):
On the current OS Explorer map the earthworths are shown as a "U-shaped" feature.

The WW2 aerial photograph from 1948 shows the earthworks in relation to the Church.

The pond and the earthworks were also the site of a Italian WW2 prisoner of war camp. The oak trees on the East bank of the pond have graffiti carvings in Italian.

Some drone photographs
This is a view of the earthworks in 2020 looking East. The earthworks appear to be completely "grown-in" and the fact that it may have been a cattle enclosure is not obvious.

Below is a photo of the pond to show it in perpective with respect to its shape and position on the OS map.
