MOTTE
The substantial earthen motte is c.75m in diameter at the base and 50m at
the summit. A curious, truncated conical mound on the summit of the motte (I)
has provoked considerable discussion in the past, but is almost certainly a
post-medieval alteration created as part of the landscaping of the castle
earthworks which appears to have taken place to create gardens around the 16th
century manor house. A structure, or perhaps a tree, is shown surmounting this
mound on Pierce's 1635 map, suggesting a contemporary ornamental function. A
quarry hollow of similar dimensions to the mound exists in the western ditch of
the inner bailey (J), and may have provided the source for the material forming
the mound. The summit of the motte bears evidence of a former palisade or wall
around its circumference. A shallow gulley and accompanying inner bank skirt
the summit of the motte (K) and are clearly evident on a number of the aerial
views. This gulley may mark the line of a timber palisade slot, or (less
likely) the robbed foundation trenches of a masonry shell keep.The motte is
surrounded by a narrow v-section ditch for most of its circumference (L), the
ditch changes character, becoming wider and shallower, around the south-western
quadrant of the motte. The motte has been carefully constructed, taking
advantage of the natural topography of the hillside upon which it lies, to
heighten the impression of the size of the defences. A terrace-way, echoing the
circuit of the motte's external ditch (M), serves to enhance the impression of
height between the terrace and the outer lip of the ditch, while the
Northwestern quadrant of the ditch has a slight counterscarp bank (N),
terminating at the top of the substantial hollow-way descending the slope
northwest of the motte.
OUTER BAILEY
The defences of the outer bailey consist of a substantial bank with external
ditch forming a roughly square enclosure c.170m on each side. At its
north-eastern corner the circuit of the outer bailey extends to the north-west
to meet the defences of the inner bailey at the entrance to the latter. The
outer bailey defences appear to post-date those of the inner bailey, but are
carefully integrated with them to form a coherent defensive structure. At its
north-east corner the bank and ditch of the outer bailey are separated from
those of the inner bailey by a narrow causeway. The form of the outer
bailey defences has undoubtedly been modified in a number of places, both by the
slighting of the bank, and by the creation of small breaches in the bank,
usually with corresponding causeways in the ditch. Nevertheless, the original
uniform, defensive layout may be clearly traced.
The
western circuit of the defences (O) lacks a bank towards its southern
end. There seems no reason to suppose that this is an original feature, as the
western circuit has ditch along its full length, and it appears most likely that
the bank has been removed at a later date, perhaps during the 16th century
modifications to the defences. At its south-eastern corner the defensive circuit
is marginally higher (P), perhaps indicating a small corner tower.
The southern circuit of the defences (Q) is clearly much altered. At its western end a narrow bank and shallow ditch preserve what may approximate the original form of the defences. East of here the bank is wide and low, and the external ditch missing. It seems most likely that here the bank has been slighted and used to fill the external ditch. It is notable that, were it not levelled, a defensive circuit at this point would at least partially block a clear view south to the Church from the site of the 16th century manor house, and it may be that the defences were altered in the 16th century to ensure such a view. A 10m wide break in both the bank and ditch marks the southern entrance to the outer bailey (R) at a point where the circuit meets Hall Lane. There seems no reason to suppose that this is other than the original entrance to the outer bailey.
The eastern defensive circuit (S) extends northwards from the southern circuit to the south-eastern corner of the inner bailey, the bank and ditch meeting the defences of the inner bailey at the northern edge of its entrance. The complex arrangement of earthworks at this point may result from a number of periods of activity, but the original intention appears to be that the outer bailey defences would meet those of the inner bailey on the northern side of the gatehouse to the inner bailey. The eastern circuit is broken at three points by narrow gaps, none of which appear original and which probably served to facilitate easy access into the part of the interior of the outer bailey which lies to the east of the Post-Medieval field boundary crossing the bailey from north to south.
The interior of the outer bailey contains a number of earthworks most of which appear to relate to the Post-Medieval activity mapped by Mark Pierce. A slight north-south break of slope (T) marks the wall or fence line shown on Mark Pierce's map. East of here several substantial mounds and hollows (U) might be associated with contemporary activity, but are perhaps most likely to be robber-pits dug to recover stone from Medieval buildings in the outer bailey. The south-western part of the outer bailey is crossed by shallow, parallel, east - west aligned ridges (V), probably the result of past cultivation and which correspond approximately with an area shown blank on Pierce's plan. No clear trace survives of the buildings shown in this area on Pierce's plan, although north of here, in the area shown as an orchard (or perhaps more likely in view of the small size of the vegetation, a vineyard) in 1635, a number of small hollows correspond approximately with a building mapped by Pierce.
East of the outer bailey there is evidence for a former additional enclosure or bailey which has previously gone without remark. The line of the southern circuit of the outer bailey defences extends for c.100m eastward from the south-east corner of the bailey (W), ending at a north-south field boundary, itself dating from at least 1635. The earthwork, consisting of a low bank with ditch on its south side, is breached in a number of places, and appears to turn slightly northwards at its eastern end.
A
further insubstantial bank, with a ditch on its northern side, extends c.35m
eastward from close to the junction of the outer and inner bailies (X). This
ditch is cut into the partially infilled outer bailey ditch, which it therefore
post-dates by a considerable period, and continues as a slight gulley with no
discernible bank for a further c.100m eastward until it meets a modern
field boundary. Together, this ditch and its southern counterpart define two
sides of an enclosure, potentially of similar dimensions to the inner bailey to
the west, though much less substantially defended. The eastern limit of this
putative enclosure is uncertain, it might coincide with the north-south field
boundary which marks the maximum extent of the southern earthwork, alternatively
it may have extended further east, to be lost entirely to recent agriculture
(the fields east of here being regularly ploughed arable). The date and
function of this enclosure are uncertain. It certainly post-dates the outer
bailey, and as the earthworks which define its extent are hardly defensive in
character, it might more readily be assigned to the Post-Medieval manorial
complex, than the Medieval castle. In 1635 the field containing the enclosure
was named as Hither Conygrey Meadow - the reference to rabbits implied by the
name may be significant as an irregular earthwork in the north-eastern quadrant
of the enclosure might conceivably be the remains of a deliberately constructed
warren.
EARTHWORKS NORTH WEST OF THE MOTTE
A number of terrace-ways descend the steep slope to the north of the castle (Y),
and provide access to the springs rising in the valley below the castle, and to
the earthworks in the field beyond the castle. There are a number of irregular
hollows (Z) at various points on the lower sloped of the hill, perhaps former
quarries, or the remains of past attempts to tap springs. North and west of
here, a variety of earthworks lie in fields named in 1635 as Great and Little
Pond Meadow, clearly they are largely to be associated with fishponds. The three
parallel linear troughs, defined by marked banks, lay at the north-eastern end
of this group (AA). The troughs are waterlogged (and water-filled in wet
weather) and fed by the adjacent springs. Such troughs are typical of the
shallow, often spring-fed, tanks (or stews) constructed for fish breeding. A
deep, rectangular pond (AB) lies immediately to the south-west of the stews, and
a shallow, irregular gulley links this pond to a shallower pond to the west (see
below). An approximately L-shaped double bank (AC) surrounds these earthworks on
their north and west sides. Two parallel banks (AD) define a broad, shallow
pond at right angles to these banks, a raised wall or dam would have been
required to secure the north-eastern side of this pond, but no trace of such a
structure survives. A C-shaped earthwork (AE) lies on the north-east side of
the shallow pond, its function is unclear.
The north-eastern boundary of this field is marked by a substantial flat-topped earthwork bank cut into by the rectangular pond (AF). The bank may have served as a dam perhaps to hold backwater to periodically flood the area enclosed to form a managed water meadow. The level surface of the field to the west of the bank supports this theory, suggesting that it is formed from an accumulation of water-lain silts deposited during periodic flooding. Alternatively the bank may have held back water to form a broad shallow pond to supply a mill located on their eastern side. Though no positive evidence for a water powered mill has yet been uncovered at Laxton it is highly likely that such a mill would have existed to serve the needs of the village prior to the introduction of the well-documented windmills sometime in the 12th century. The valley of Radbeck, close to the castle represents a ideal location for such a mill.
Whatever their original function it appears likely that the bank predate the construction of the fishponds. The large rectangular pond is a later addition, breaching the bank at its mid point, and the bank appear to have been reduced in size immediately to the north and south of the pond, perhaps at the same time that the fish ponds to the west were constructed.
