Reasons for Designation
Motte and bailey castles are medieval fortifications introduced into Britain
by the Normans. They comprised a large conical mound of earth or rubble, the
motte, surmounted by a palisade and a stone or timber tower. In a majority of
examples an embanked enclosure containing additional buildings, the bailey,
adjoined the motte. Motte castles and motte-and-bailey castles acted as
garrison forts during offensive military operations, as strongholds, and, in
many cases, as aristocratic residences and as centres of local or royal
administration. Built in towns, villages and open countryside, motte and
bailey castles generally occupied strategic positions dominating their
immediate locality and, as a result, are the most visually impressive
monuments of the early post-Conquest period surviving in the modern landscape.
Over 600 motte castles or motte-and-bailey castles are recorded nationally,
with examples known from most regions. As one of a restricted range of
recognised early post-Conquest monuments, they are particularly important for
the study of Norman Britain and the development of the feudal system. Although
many were occupied for only a short period of time, motte castles continued to
be built and occupied from the 11th to the 13th centuries, after which they
were superseded by other types of castle.
Cymbeline's Castle is a good example of a smaller motte and bailey castle with
both the major components extremely well preserved, and having additional
features such as the entrance and approach.
The interior of the baileys and top of the motte will retain buried evidence
for former structures, including the foundations of timber defences
strengthening the earthworks. The surrounding ditches contain deep deposits of
accumulated silts from which may be recovered both artefacts relating to the
period of use, and environmental evidence illustrating the developing
appearance of the landscape around the castle during its construction and
occupation. The buried landsurface beneath the motte and ramparts is of
particular importance in this respect, demonstrating the former land use, and
perhaps retaining evidence of Roman or prehistoric occupation suggested by
The commanding location of the castle demonstrates its strategic role in the
years following the Norman Conquest, in particular dominating the
communication routes which followed the edge of the Chiltern escarpment. It
also lies in close proximity to a large medieval moated complex at the foot of
Little Kimble Hill, allowing comparisons between the castle and this less
defensive settlement which will provide valuable information about the
changing lifestyle of the medieval aristocracy.
Cymbeline's Castle occupies a prominent position on the tip of a spur below
Beacon Hill, on the northern edge of the Chiltern escarpment. This commanding
location overlooks the villages of Ellesborough and Little Kimble and provides
wide views across the Vale of Aylesbury.
The main stronghold, a conical mound (or motte), measures about 42m in
diameter and between 6m and 8m in height in relation to the natural slope of
the spur. A level area on the summit, c.15m wide, indicates the dimensions of
the timber tower which originally would have stood here, and there is a
smaller semicircular annexe cut into the slope below the summit on the
northern side. A narrow terrace, c.5m in width, flanks the base of the mound
on the western side of the motte, truncating the steep gradient at the end of
the spur. The remaining three quarters of the circumference is encircled by a
ditch, averaging 3m wide and 1m deep, separating the motte from two adjacent
enclosures, or baileys.
The larger, southern bailey is roughly square in plan, measuring about 40m
across, and enclosed by a broad ditch, 1.2m deep, on the north eastern and
south eastern sides. The northern arm is joined to the motte ditch, and both
arms contain deep deposits of accumulated silt and humus. The south western
side of the bailey was sited to exploit the natural defence provided by a
steep slope leading into Velvet Lawn, a narrow coombe flanking the spur. This
slope is, however, augmented by an artificial scarp, 2.5m high; with the
terrace surrounding the motte continuing along its base. The bailey interior
slopes gently from north to south and is bounded by an internal bank averaging
8m in width and 1.7m high. The position of a bridge, spanning the ditch and
ascending the motte, is indicated by a break in this bank near the northern
end of the intervening section.
The northern bailey is thought to be a later development, added to the north
western sides of the motte and the earlier, southern bailey. The defences of
the two baileys are separated by a narrow causeway which leads into the
northern bailey from the east. This causeway, however, remains level with the
pasture on the back of the spur, and may be a relatively recent addition. The
northern bailey is rectangular, measuring c.48m by 20m; and is similarly
defined by a broad ditch and an internal bank, which survives around the
eastern side of the enclosure. There are traces of a second causeway near the
centre of the north eastern arm, to the south of the terminal of the internal
bank. This is approached from the north by a slightly terraced trackway which
is aligned with the northern end of an embanked hollow way leading down the
hillside to the north west. Together, the track and hollow way skirt around a
narrow coombe on the northern side of the spur, providing the most logical
approach to the castle from the foot of the escarpment.
Quantities of pottery fragments dating from the 13th to 15th centuries have
been discovered in the dark soil which covers the interiors of the baileys.
Evidence of earlier activity is provided by finds of Iron Age and
Romano-British pottery from the adjacent area to the east, in addition to a
single Iron Age sherd found within the castle itself.
The terms `Cymbeline's Castle', `Cymbeline's Mount' and `Belinus's Castle'
have been recorded since the mid 19th century; although sometimes also applied
to another hilltop 1km to the south. They are said to be derived from a local
tradition that the Iron Age king, Cunobelinus (Shakespeare's Cymbeline),
resided in these hills. This tradition may be a Victorian invention, although
the same source has been suggested as the basis of the much older place-name
`Kimble' which occurs locally as the name of both villages and hills.
The terraced approach, together with a sample of the hollow way, is included
in the scheduling in order to preserve the archaeological relationship between
these features and the castle. All fences and fence posts are excluded from
the scheduling although the ground beneath is included.
The site of the monument is shown on the attached map extract.
It includes a 2 metre boundary around the archaeological features,
considered to be essential for the monument's support and preservation.
