PREHISTORIC DERBYSHIRE BURIAL SITES

Barrow, in England, ancient burial place covered with a large mound of earth. In Scotland, Ireland, and Wales the equivalent term is cairn. Barrows were constructed in England from Neolithic (c. 4000 BC) until late pre-Christian (c. AD 600) times. Barrows of the Neolithic Period were long and contained the various members of a family or clan, while those of the Early Bronze Age (c. 1900 BC) were round in shape and were used to bury a single important individual, perhaps a chief or clan leader. The bodies were placed in stone or wooden vaults, over which large mounds of soil were heaped. Both types of barrows continued to be used in England until the advent of Christianity. Their sites are most common in the county of Wiltshire.

From Encyclopaedia Britannica –
Cairn, a pile of stones that is used as a boundary marker, a memorial, or a burial site. Cairns are usually conical in shape and were often erected on high ground. Burial cairns date primarily from the Neolithic Period and the Early Bronze Age. Cairns are still used in some parts of the world as burial places, particularly where the soil is difficult to excavate or where wild animals might disturb the body. The term cairn is sometimes used interchangeably with barrow, and its usage is not well defined.

from Historic England –
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 protection.
