Summary

Banjo enclosure and associated enclosure 900m WNW of Frogmore Farm.

Reasons for Designation

Cranborne Chase is an area of chalkland well known for its high number, density and diversity of archaeological remains. These include a rare combination of Neolithic and Early Bronze Age sites, comprising one of the largest concentrations of burial monuments in England, the largest known cursus (a linear ritual monument) and a significant number and range of henge monuments (Late Neolithic ceremonial centres). Other important remains include a variety of enclosures, settlements, field systems and linear boundaries which date throughout prehistory and into the Romano-British and medieval periods. This high level of survival of archaeological remains is due largely to the later history of the Chase. Cranborne Chase formed a Royal Hunting Ground from at least Norman times, and much of the archaeological survival within the area resulted from associated laws controlling land-use which applied until 1830. The unique archaeological character of the Chase has attracted much attention over the years, notably during the later 19th century, by the pioneering work on the Chase of General Pitt-Rivers, Sir Richard Colt Hoare and Edward Cunnington, often regarded as the fathers of British archaeology. Archaeological investigations have continued throughout the 20th century and to the present day. Banjo enclosure is the term used by archaeologists for a distinctive type of prehistoric settlement. They were mostly constructed and used during the Middle Iron Age (400-100 BC), although some remained in use up to the time of the Roman Conquest (AD 43). Typical banjo enclosures have an oval or sub- rectangular central area, rarely greater than 0.4ha in size, encircled by a broad, steep-sided ditch and an external bank. There is characteristically a single entrance, approached by an avenue up to 90m long formed by out-turnings of the enclosure's ditch. The entrance to the avenue sometimes has further `antennae' ditches, giving a funnel-like appearance; or it may be connected to a transverse linear ditch. The enclosures resemble banjos when viewed in plan, hence their name. Excavated banjo enclosures have been found to contain evidence of habitation, evidence for wooden structures provided by post holes and drainage gullies, and storage and refuse pits. These features, together with the ditches, generally contain abundant artefacts, and can provide environmental evidence illustrating the landscape in which the monument was set, and the economy of its inhabitants. The enclosures are often associated with other types of Iron Age monuments, including other enclosures, field systems, trackways and other unenclosed settlement forms. Together, these monument types provide information concerning the diversity of social organisation and farming practices amongst prehistoric communities. Banjo enclosures are largely known from cropmarks and soil marks recorded from the air, although a few survive as earthworks. Over 200 examples are recorded nationally, the majority of which are located in Wessex and around the upper Thames Valley: particular concentrations have been noted on the chalk downland of Hampshire. Elsewhere they are very rare, with isolated examples recorded in the Midlands and the north. The existence of further examples is likely to be confirmed by aerial photographic survey. Despite cultivation the banjo enclosure and associated enclosure 900m WNW of Frogmore Farm survive comparatively well and will contain archaeological and environmental evidence relating to their construction, longevity, social organisation, agricultural practices, trade, domestic arrangements and overall landscape context.

Details

This record was the subject of a minor enhancement on 18 February 2016. This record has been generated from an "old county number" (OCN) scheduling record. These are monuments that were not reviewed under the Monuments Protection Programme and are some of our oldest designation records.

This monument includes a banjo enclosure and an associated circular enclosure situated on gently south east facing slopes in rolling countryside. The banjo enclosure and circular enclosure survive as completely buried features, deposits and layers which are visible as crop and soil marks on aerial photographs. The banjo enclosure survives as an irregular shaped enclosure which measures up to 90m wide and is defined by a ditch with a tapering curving funnel shaped entrance to the south east. This curves back to the north and incorporates a second circular enclosure of up to 30m in diameter. Both the banjo and circular enclosures also contain clearly defined pits.
