Details

This monument includes a large Iron Age multiple enclosure fort, located
on a broad spur north of Malborough village. It commands a high and prominent
location with wide local views.
The monument survives as a series of three semi-concentric enclosures, partly
preserved in later hedgebanks, surrounding a small ovoid central enclosure,
now largely levelled. The best preserved rampart of the fort forms the north
west side of this inner enclosure and is univallate. The hillside here drops
steeply away, but the north east side slopes gently, while the south and west
sides are virtually level. These sides of the fort were defended by the three
outworks. The original main entrance appears to have been at the extreme
eastern corner of the outer rampart, where the rampart ends turn in slightly.
A faint hollow way is visible within this entrance. Another entrance, 110m to
the north west is of later date. A hollow way followed by a modern footpath
climbs up through it from the north, but the rampart here has no obvious
break. A third entrance at the north west corner of the site has traces of a
hornwork below it, projecting from the outer rampart and curving round to the
east. Its western part is followed by a later hedgebank.
The rampart on the north west side of the inner enclosure is about 5m wide,
rising 0.8m from the interior and falling steeply 3.5m to the outer ditch.
This is 9m wide, and up to 0.7m deep. A counterscarp bank with an outer glacis
is 13m wide by up to 1m high. Elsewhere, the ramparts which survive in later
hedgebanks are typically about 2m wide, rising from 0.8m to 1.5m from the
interior and falling 1.5m to 2.5m to the exterior. Of the ploughed ramparts,
the outer circuit on the west has a bank 9m wide by up to 0.5m high, with an
outer ditch 7m wide and 0.4m deep. An upcast bank is 10m wide and 0.3m high.
The intermediate ramparts on the south side are only visible as changes in the
level of the field, on average about 0.4m high, although their ditches can be
seen on aerial photographs.
Within the inner circuit is a brick bunker associated with the use of the site
as a radar station during World War II. The bunker, now used as a reservoir,
is 9m wide by 13m long, embanked with earth, and is 3m high with a flat
concrete roof. Traces of a service road pass along the inside of the former
southern rampart to the east side of the site.
All fence posts are excluded from the scheduling, although the ground beneath
them is included.

Reasons for Scheduling

Multiple enclosure forts comprise an inner and one or more outer enclosed
areas, together measuring up to c.10ha, and defined by sub-circular or sub-
rectangular earthworks spaced at intervals which exceed 15m; the inner
enclosure is usually entirely surrounded by a bank and ditch. The forts date
mainly to the Late Iron Age (350 BC-c.AD 50) and in England usually occur in
the south west. Most are sited on hillslopes overlooked by higher ground near
a water supply, and many were apparently used for periods of up to 250 years.
The outer enclosures of the forts are usually interpreted as areas set aside
for the containment of livestock, whilst the inner enclosures are generally
thought to have been the focus of occupation.
The earthworks usually include a bank with an outer V-shaped ditch 1m-3m deep.
Entrances are generally single gaps through each line of defence, often
aligned to create a passage from the outer to the inner enclosure, although
there are a few examples where entrances through successive earthworks are not
in alignment. Occasionally the interval between the gaps is marked by inturned
ramparts or low banks and ditches, while the outer entrance may be screened by
a short length of earthwork. Excavations within the inner enclosures have
revealed a range of buildings and structures, including circular structures,
hearths, ovens and cobbled surfaces as well as occasional small pits and large
depressions which may have functioned as watering holes.
Multiple enclosure forts are relatively rare with only around 75 examples
recorded in England, mostly in Devon and Cornwall. Outside these counties
their distribution becomes increasingly scattered and the form and
construction methods more varied. They are important for the study of
settlement and stock management in the later prehistoric period, and most
well-preserved examples will be identified as being of national importance.

Despite the reduction of many of the internal ramparts by ploughing, the Iron
Age hillfort known as Burleigh Dolts, 280m south east of Burleigh Farm
survives well. Substantial lengths of the fort's outer enclosure survive,
fossilised in later hedgebanks. The fort's design is unusual in the locality,
where a single line of defence is normal. The fort interior, its ramparts and
their buried ditches will contain archaeological and environmental information
relating to the use and construction of the fort and the landscape in which it
was sited.
