Details

The monument includes an Iron Age hillfort situated on the summit of a steep
inland spur, surrounded on three sides by the valley of a stream, which curves
around its base.
The monument survives as an oval enclosure with a ditch and outer bank. It
is aligned north west-south east. The internal dimensions of the enclosed area
are 86m long from north west to south east, and 47m wide. The surrounding
rampart bank is best preserved on the southern side where it is 2.6m wide and
0.3m high internally. Beyond the enclosure and defining its extent is a ditch,
and outside this lies an outer bank. The ditch is up to 3.3m wide, and the
outer bank up to 4.2m wide and to a maximum 2.3m high.

Reasons for Scheduling

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 150 to 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 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. 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.

The hillfort in Ten Oaks Wood survives comparatively well and contains
archaeological and environmental information relating to the settlement and
exploitation of this area during the Iron Age.
