Details

The monument includes a large prehistoric cairn located in a prominent
position in open moorland. Its size, relative isolation, and position in the
landscape indicate that it is a funerary monument.
The cairn is slightly ovoid in shape and measures 18m by 15m and stands
approximately 0.7m high. In the centre of the cairn are small depressions
which may be minor, undocumented excavations or the results of stone robbing.
Apart from the depressions, and minor damage to the sides of the cairn, it is
a well preserved example and is therefore likely to retain undisturbed burial
remains. The monument has a complex structure consisting of a flat-topped
platform with an inner cairn of approximately 11m diameter situated on top of
it. The cairn is interpreted as dating from the Bronze Age and it stands close
to evidence for extensive contemporary settlement and agriculture on the same
moorlands.

Reasons for Scheduling

The East Moors in Derbyshire includes all the gritstone moors east of the
River Derwent. It covers an area of 105 sq km, of which around 63% is open
moorland and 37% is enclosed. As a result of recent and on-going
archaeological survey, the East Moors area is becoming one of the best
recorded upland areas in England. On the enclosed land the archaeological
remains are fragmentary, but survive sufficiently well to show that early
human activity extended beyond the confines of the open moors.
On the open moors there is significant and well-articulated evidence over
extensive areas for human exploitation of the gritstone uplands from the
Neolithic to the post-medieval periods. Bronze Age activity accounts for the
most intensive use of the moorlands. Evidence for it includes some of the
largest and best preserved field systems and cairnfields in northern England
as well settlement sites, numerous burial monuments, stone circles and other
ceremonial remains which, together, provide a detailed insight into life in
the Bronze Age. Also of importance is the well preserved and often visible
relationship between the remains of earlier and later periods since this
provides an insight into successive changes in land use through time.
A large number of the prehistoric sites on the moors, because of their rarity
in a national context, excellent state of preservation and inter-connections,
will be identified as nationally important.

Round cairns are prehistoric funerary monuments dating to the Bronze Age
(c.2,000-700 BC). They were constructed as stone mounds covering single or
multiple burials. These burials may be placed within the mound in stone lined
compartment called cists. They are a relatively common feature of the uplands
and are the stone equivalents of the earthen round barrows of the lowlands.
Their considerable variation in form and longevity as a monument type provide
important information on the diversity of beliefs and social organisation
amongst prehistoric communities. They are particularly representative of
their period and a substantial proportion of surviving examples are considered
worthy of protection.
The cairn 800m WSW of Offerton House is important as a relatively rare, near-
complete example and as such is likely to contain undisturbed buried remains.
