Henge enclosure


There are three related types of Neolithic earthwork that are all sometimes loosely called henges. The essential characteristic of all three types is that they feature a ring bank and ditch, but with the ditch inside the bank rather than outside. Due to the poor defensive utility of an enclosure with an external bank and an internal ditch, henges are not considered to have served a defensive purpose (cf. circular rampart). The three types are as follows, with the figure in brackets being the approximate diameter of the central flat area:

The word henge is a backformation from Stonehenge, the famous monument in Wiltshire. Stonehenge is not a true henge as its ditch runs outside its bank, although there is a small extant external bank as well. The term was first coined in 1932 by Thomas Kendrick, who later became the Keeper of British Antiquities at the British Museum.

Henges may be classified as follows:

Sub groups exist for these when two or three internal ditches are present rather than one. Henges are usually associated with the Late Neolithic or Early Bronze Age, and especially with the pottery of this period: Grooved Ware, Impressed Wares (formerly known as Peterborough Ware), and Beakers. Sites such as Stonehenge also provide evidence of activity from the later Bronze Age Wessex culture.

Henges often contain evidence of a variety of internal features, including timber or stone circles, pits, or burials, which may pre- or post-date the henge enclosure. A henge should not be confused with a stone circle within it, as henges and stone circles can exist together or separately. At Arbor Low in Derbyshire, all the stones except one are laid flat and do not seem to have been erected, as no stone holes have been found. Elsewhere, often only the stone holes remain to indicate a former circle.

Some of the best-known henges are at:

Henges sometimes formed part of a ritual landscape or complex, with other Neolithic and Bronze Age monuments inside and outside the henge. Earlier monuments associated with a later henge might include Neolithic monuments such as a cursus (e.g., at Thornborough Henges the central henge overlies the cursus), or a long barrow such as the West Kennet Long Barrow at Avebury, Wiltshire, or even, as in the case of Stonehenge, Mesolithic post holes. Later monuments added after the henge was built might include Bronze Age cairns as at Arbor Low. Examples of such ritual landscapes are:
