The monument includes Lambert's Castle, a large univallate Iron Age hillfort
located at the end of a spur 425m west of Nash Farm, one of four hillforts
overlooking the western end of the Marshwood Vale. Two other hillforts occupy
prominent hilltops within 8km to the east. All these hillforts are the subject
of separate schedulings.
Within the hillfort are a bowl barrow, the remains of a fair site which may
date back to the medieval period, and a 19th century telegraph station. The
interior has been divided into small fields defined by stone walls dating to
the 19th century at the time of Enclosure and Tithe Apportionment. These are
shown on the Tithe map of 1844, but not on an estate map dating to 1769
showing the hillfort.
The hillfort has a rampart 8m wide rising up to 3m above the base of the 4m
wide and 1.5m deep external ditch, built along the edge of the escarpment and
across the level ridge at the southern end, enclosing a rectangular area about
4.7ha in size. There is a counterscarp bank on the outside of the ditch
visible intermittently around the enclosure, 2m wide and 0.3m high. These
earthworks have been disturbed by 19th century field walls which have often
been cut into the scarp of the bank or ditch. On the southern side a gap in
the ramparts with a corresponding causeway across the ditch provides access
across the level neck of the spur. The entrance gap is 12m wide but may have
been disturbed. The earthworks on this side are more substantial than
elsewhere in the hillfort. A second entrance on the northern side may have
been original, consisting of a causeway across the ditch with a hollow way
continuing into the interior. Earthworks to the west of this hollow
way may suggest an inturned entrance. A narrow causeway across the ditch at
the north west corner of the hillfort provides access to the interior along a
footpath and is thought to be modern. Following storm damage in January 1990 a
section across the rampart in the north west corner of the hillfort was
recorded by the National Trust before reinstatement. This indicated that there
were two or possibly three phases of construction, the earliest being a box
rampart of dump construction, built on the old land surface, with timber
palisades lining the inner and outer faces and possibly a stone facing on the
outside. No dateable finds were recovered.
Near the southern end of the hillfort there is a Late Neolithic to Bronze Age
bowl barrow which has been disturbed by the later fair activities. It is now
an irregular mound but was originally a maximum of 13m in diameter and is
0.75m high. There are no visible traces of a quarry ditch surrounding the
mound but this will survive as a buried feature.
The site of the fair lies in the centre of the hillfort near the southern
entrance. Low banks, about 0.2m high, forming a regular rectangular grid
pattern, can be seen to the west of, and partly disturbing, the bowl barrow,
and probably represent the remains of fair stalls. The fair house was thought
to be behind the southern rampart east of the entrance where there is a square
depression 15m across. To the south of the stalls is a raised stony platform
about 6m square and 0.2m high. Its date and function are not known but it was
probably connected with the fair. In the south west corner of the hillfort are
two small rectangular fields bound by banks, 3m wide and up to 1m high, with
traces of ditches on both sides 1m wide and 0.3m deep. The southern field has
a double bank on its eastern side, with a ditch on both sides of the banks and
a gap of 2.3m between them. The date of these fields is not known but they
have generally been considered to be of medieval origin and an association
with the fair is likely. The earliest reference to a fair at Lambert's Castle
was in 1709 when a grant was obtained to hold an annual fair on the Wednesday
before the feast of St John the Baptist (24th June). However, as the site is
fairly isolated, and comparing it with other medieval fairs located in
hillforts, it is possible that it was chosen for the site of the 18th century
fair because of an existing tradition. A fair continued to be held in June on
the hill top until about 1947, with horse races taking place outside the hill
fort. A second fair in September was also held on the site for a while in the
19th century. Although the fair activities extended along the ridge to the
south outside the hillfort only those features contained within the ramparts
are included in the scheduling.
Towards the north east corner of the hillfort is the site of a telegraph
station which was built in 1806 as part of a chain of similar stations between
Plymouth and the Admiralty. The site is overgrown making it difficult to
verify any surface features, but deposits relating to the building will
survive below ground.
All fence and gate posts, and post-medieval field walls, are excluded from the
scheduling, although the ground beneath these features 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.

Reasons for Scheduling

Large univallate hillforts are defined as fortified enclosures of varying
shape, ranging in size between 1ha and 10ha, located on hilltops and
surrounded by a single boundary comprising earthworks of massive proportions.
They date to the Iron Age period, most having been constructed and used
between the fourth century BC and the first century AD, although evidence for
earlier use is present at most sites. The size of the earthworks reflects the
ability of certain social groups to mobilise the labour necessary for works on
such a monumental scale, and their function may have had as much to do with
display as defence. Large univallate hillforts are also seen as centres of
redistribution, both for subsistence products and items produced by craftsmen.
The ramparts are of massive proportions except in locations where steepness of
slope precludes easy access. They can vary between 6m and 20m wide and may
survive to a height of 6m. The ditches can measure between 6m and 13m wide and
between 3m and 5m deep. Access to the interior is generally provided by one or
two entrances which often take the form of long passages formed by inturned
ramparts and originally closed by a gate located towards the inner end of the
passageway. The entrance may be flanked by guardrooms and/or accompanied by
outworks. Internal features included timber or stone round houses; large
storage pits and hearths; scattered postholes, stakeholes and gullies; and
square or rectangular buildings supported by four to six posts, often
represented by postholes, and interpreted as raised granaries. Large
univallate hillforts are rare with between 50 and 100 examples recorded
nationally. Most are located within southern England where they occur on the
chalklands of Wessex, Sussex and Kent. The western edge of the distribution is
marked by scattered examples in north Somerset and east Devon, while further
examples occur in central and western England and outliers further north.
Within this distribution considerable regional variation is apparent, both in
their size, rampart structure and the presence or absence of individual
components. In view of the rarity of large univallate hillforts and their
importance in understanding the organisation and regional structure of Iron
Age society, all examples with surviving archaeological remains are believed
to be of national importance.

Lambert's Castle hillfort is well preserved and will contain archaeological
deposits providing information about Iron Age society, economy and
environment. It is one of four hillforts overlooking the western end of the
Marshwood Vale within a distance of 8km, which is an unusual concentration.
Bowl barrows are the most numerous form of round barrow, and are funerary
monuments dating from the Late Neolithic period to the Bronze Age, with most
examples constructed in the period 2400-1500 BC. They were constructed as
earthern or rubble mounds, sometimes ditched, which contained single or
multiple burials. Despite disturbance, this example will retain archaeological
remains. The location of the fair in the hillfort provides an unusual
association and information relating to society and economy in the post-
medieval and possibly medieval period will be preserved. The telegraph station
was part of an extensive warning system important during the Napoleonic wars.
