Reasons for Designation
Slight univallate hillforts are defined as enclosures of various shapes,
generally between 1ha and 10ha in size, situated on or close to hilltops and
defined by a single line of earthworks, the scale of which is relatively
small. They date to between the Late Bronze Age and Early Iron Age (eighth -
fifth centuries BC), the majority being used for between 150 and 200 years
prior to their abandonment or reconstruction. Slight univallate hillforts have
generally been interpreted as stock enclosures, redistribution centres, places
of refuge and permanent settlements. The earthworks generally include a
rampart, narrow level berm, external ditch and counterscarp bank, while access
to the interior is usually provided by two entrances comprising either simple
gaps in the earthwork or an inturned rampart. Postholes revealed by excavation
indicate the occasional presence of portal gateways while more elaborate
features like overlapping ramparts and outworks are limited to only a few
examples. Internal features include square or rectangular buildings supported
by four to six postholes and interpreted as raised granaries, timber or stone
round houses, large storage pits and hearths as well as scattered postholes,
stakeholes and gullies. Slight univallate hillforts are rare with around 150
examples recorded nationally. Although on a national scale the number is low,
in Devon they comprise one of the major classes of hillfort. In other areas
where the distribution is relatively dense, for example, Wessex, Sussex, the
Cotswolds and the Chilterns, hillforts belonging to a number of different
classes occur within the same region. Examples are also recorded in eastern
England, the Welsh Marches, central and southern England. In view of the
rarity of slight univallate hillforts and their importance in understanding
the transition between Bronze Age and Iron Age communities, all examples which
survive comparatively well and have potential for the recovery of further
archaeological remains are believed to be of national importance.
Eston Nab is the only surviving hillfort of any date in the county of
Cleveland; it is very well preserved and, although it has been subject to
partial excavation, the extent of disturbance is limited and its
archaeological deposits remain largely intact. Evidence relating to its
construction and to the complex history of the entire hilltop as well as the
nature and duration of its use will be preserved within the archaeological
deposits. Evidence relating to the Bronze Age environment around the monument
and of the wider landscape will also survive. The importance of this monument
is enhanced by the survival of contemporary settlements and funerary monuments
in the vicinity; such evidence provides a clear indication of the extent of
Bronze Age settlement and activity in the area and has the potential to
increase greatly our knowledge of Bronze Age society.
Details
The monument includes a Late Bronze Age hillfort, a palisaded settlement, at
least one Bronze Age bowl barrow and a 19th century beacon, situated on a
steep, north facing scarp edge with extensive views in all directions. The
hillfort, semi-circular in shape, has maximum dimensions of 250m from
east-west and 120m from north-south within a defensive bank, ditch and
counterscarp bank. The defensive bank survives to a maximum height of 1m and
the ditch, from which the material to build the bank was quarried, varies in
width from 4-6 metres and is on average 1m deep. A break for the original
entrance appears on the south-eastern side. A counter-scarp bank, constructed
of surplus material quarried from the ditch, lies outside of the main
defences; it is up to 4m wide and survives to a height of 1m. Within the
defensive circuit there are several features relating to the use of the
hillfort, including at least one round house revealed by excavation. A stone
walled enclosure, set against the southern part of the bank is contemporary
with or later than the hillfort. Excavation has shown that the first activity
on the hilltop was in the Early Bronze Age. A low fragment of the mound of a
bowl barrow constructed during this period can be seen near the scarp edge.
Flint tools of broadly similar date were also found. The hilltop was first
enclosed by two phases of wooden palisade during the Late Bronze Age before
the construction of the more massive bank and ditch visible today. Although
the palisades are no longer visible at ground level, their foundation slots
survive as buried features. In the south-eastern section of the hillfort,
where a modern monument marks its position there are the remains of a square,
stone beacon. This is situated within a small quadrangular enclosure and is
believed to have been erected in the early 19th century when it served as a
beacon or lookout post during the Napoleonic wars. The Eston beacon monument
and the trig point are excluded from the scheduling, although the ground
beneath these features is included.
