(OS 1:10000 SP 75 NW)
The extreme N. end of the old parish of Rothersthorpe, a small
triangular area covering about 50 hectares, now lies within Northampton.
For the remainder of the parish, see RCHM Northamptonshire IV, 127–31.
It is almost flat ground, mainly Upper Lias Clay with glacially-derived
sands and gravels along its E. edge.
Prehistoric or Roman
(1) Enclosures (SP 723577 and 722578), lie 300 m. N. of the M1,
on glacial sand and gravel, at 64 m. above OD. Air photographs (in NMR)
show a sub-rectangular enclosure covering about 1 hectare whose N.E. side
appears to coincide with the existing stream. Within it are some
indeterminate cropmarks, some of which may be relatively recent quarry
pits (NDC A70). A possible second enclosure lies immediately to the N.W.
