An area of improved grazing marsh located to the west of Copt Hall. Substantial earthworks are still visible, associated with a series of ponds, two mounds may be Red Hills.

Historic environment character
Area of improved grassland no boundary ditches. Substantial earthworks are still visible. An earthwork survey concluded that the most definate manmade features in the field were two ponds. The weir element in the placename would suggest either the control of water levels of the ponds through the use of banks or sluices, or 'weir' could simply refer to embankments at the sides of the creeks. The weir element could also potentially refer to a fish weir, a fixed fishing structure. The other potential features are two mounds which may perhaps be the remnants of red hills.

Character of vegetation
Improved grassland. Dominated by Bent grasses Agrostis spp, Meadow grass Poa spp., Meadow barley Hordeum secalinum, Perennial rye-grass Lolium perenne and Red Fescue Festuca rubra. Bordered by hedgerow, small clump of trees in centre.
