Details

The monument includes two round barrows aligned north-south and visible as
cropmarks on aerial photographs and as slight earthworks on the ground. The
barrows are located on a break of slope facing south-east overlooking the
River Kennet and Avebury.
The northern barrow mound has a diameter of 27m and is surrounded by a quarry
ditch c.3m across. The southern mound is 15m in diameter and has a quarry
ditch c.2m across. Although no longer visible at ground level, the ditches
provided material used in the construction of the mounds. Since construction
they have been gradually infilled and now survive as buried features.
Excluded from the scheduling is the fence line which crosses the monument from
north to south but the ground beneath the feature is included.

MAP EXTRACT
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

A small number of areas in southern England appear to have acted as foci for
ceremonial and ritual activity during the Neolithic and Early Bronze Age
periods. Two of the best known and earliest recognised, with references in the
17th century, are around Avebury and Stonehenge, now jointly designated as a
World Heritage Site. In the Avebury area, the henge monument itself, the West
Kennet Avenue, the Sanctuary, West Kennet long barrow, Windmill Hill
causewayed enclosure and the enigmatic Silbury Hill are well-known. Whilst the
other Neolithic long barrows, the many Bronze Age round barrows and other
associated sites are less well-known, together they define one of the richest
and most varied areas of Neolithic and Bronze Age ceremonial and ritual
monuments in the country. Round barrow cemeteries date to the Bronze Age
(2000-700 BC). They comprise closely-spaced groups of up to 30 round barrows -
rubble or earthen mounds covering single or multiple burials. Most cemeteries
developed over a considerable period of time, often many centuries, and in
some cases acted as a focus for burials as late as the early medieval period.
They exhibit considerable diversity of burial rite, plan and form, frequently
including several different types of round barrow and occasionally associated
with earlier long barrows. Where investigation beyond the round barrows has
occurred, contemporary or later `flat' burials between the barrow mounds have
often been revealed. Round barrow cemeteries occur across most of lowland
England with a marked concentration in Wessex. In some cases they are
clustered around other important contemporary monuments, as is the case both
here and at Stonehenge. Often occupying prominent locations, they are a major
historic element in the modern landscape, while their diversity and their
longevity as a monument type provide important information on the variety of
beliefs and social organisation amongst early prehistoric communities. All
examples are considered worthy of protection.

The two Bronze Age round barrows 200m SSE of Windmill Hill survive as part of
a nationally important round barrow cemetery and will contain archaeological
and environmental evidence relating to the development of the cemetery and the
landscape in which it was constructed.
