Reasons for Designation
Bowl barrows, the most numerous form of round barrow, are funerary monuments
dating from the Late Neolithic period to the Late Bronze Age, with most
examples belonging to the period 2400-1500 BC. They were constructed as
earthen or rubble mounds, sometimes ditched, which covered single or multiple
burials. They occur either in isolation or grouped as cemeteries and often
acted as a focus for burials in later periods. Often superficially similar,
although differing widely in size, they exhibit regional variations in form
and a diversity of burial practices. There are over 10,000 surviving bowl
barrows recorded nationally (many more have already been destroyed), occurring
across most of lowland Britain. Often occupying prominent locations, they are
a major historic element in the modern landscape and their considerable
variation of form and longevity as a monument type provide important
information on the diversity of beliefs and social organisations amongst early
prehistoric communities. They are particularly representative of their period
and a substantial proportion of surviving examples are considered worthy of
Although the barrow has been partially altered by agricultural activity, it was comparatively well documented during a campaign of fieldwork in the 19th century and below-ground remains will survive. The monument is one of a closely associated group of barrows which have further associations with broadly contemporary boundary earthworks on Birdsall Wold. Similar groups of monuments are also known from other parts of the Wolds and from the southern edge of the North York Moors. Such associations between monuments offer important scope for the study of the division of land for social, ritual and agricultural purposes in different geographical areas during the prehistoric period.
The monument includes a bowl barrow situated on a plateau at the north side of
Hanging Grimston Wold, close to the head of Brownmoor Dale. It is one of a
number of prehistoric monuments in the vicinity of Aldro Farm.
Although altered over the years by agricultural activity and no longer visible
at the surface, an infilled ditch, with a diameter of 22m, which encircled the
barrow has been observed on aerial photographs and it was recorded by J R
Mortimer in 1868. Mortimer's excavation of the centre of the mound revealed a
single burial; other buried features, including burials and the infilled
ditch, will remain undisturbed.
