Reasons for Designation

The Isles of Scilly, the westernmost of the granite masses of south west England, contain a remarkable abundance and variety of archaeological remains from over 4000 years of human activity. The remote physical setting of the islands, over 40km beyond the mainland in the approaches to the English Channel, has lent a distinctive character to those remains, producing many unusual features important for our broader understanding of the social development of early communities. Throughout the human occupation there has been a gradual submergence of the islands' land area, providing a stimulus to change in the environment and its exploitation. This process has produced evidence for responses to such change against an independent time-scale, promoting integrated studies of archaeological, environmental and linguistic aspects of the islands' settlement. The islands' archaeological remains demonstrate clearly the gradually expanding size and range of contacts of their communities. By the post- medieval period (from AD 1540), the islands occupied a nationally strategic location, resulting in an important concentration of defensive works reflecting the development of fortification methods and technology from the mid 16th to the 20th centuries. An important and unusual range of post- medieval monuments also reflects the islands' position as a formidable hazard for the nation's shipping in the western approaches. The exceptional preservation of the archaeological remains on the islands has long been recognised, producing an unusually full and detailed body of documentation, including several recent surveys. Stone hut circles are what remain of the round houses of early inhabitants on the Isles of Scilly. Excavation has shown that round houses were built on the islands from the Bronze Age to the early medieval period (c.2000 BC-AD 1066), though during the Romano-British period (AD 43-400) complex forms were developed with multiple rooms and annexes, classified separately as `courtyard houses'. Stone hut circles survive with rubble or earth and rubble walls or banks defining circular or ovoid internal areas. These are usually levelled and range from 2.5-13m across, though they are generally 3-5m across. The walls may incorporate natural ground-fast boulders or outcrops and sometimes have a facing of edge-set slabs, large blocks or occasionally of coursed rubble walling along one or both faces. Some hut circle walls show entrance gaps, 0.5-2m wide, sometimes flanked by end-set slabs or blocks. Remains of roofing are not preserved but excavations have revealed post- and stake-holes for roof supports and internal subdivisions. Excavation has also revealed a range of domestic artefacts and, in a small number of later examples, evidence for metal working. The deposits within and around hut circles may also include quantities of midden material. Stone hut circles may occur singly or in small or large groups, either closely spaced or dispersed. At least 136 hut circles are recorded on the Isles of Scilly. These are widely distributed but are more likely to be found towards the lower land, the coastal margins and the inter- tidal zone, reflecting the subsequent submergence of much low-lying land that formed the original landscape context in which many such settlements were built. Hut circles may be associated with broadly contemporary field systems and funerary monuments, while some examples dating to the Romano-British and early medieval period are included within sites forming religious foci. They embody a major part of our evidence on the economy and lifestyle of the islands' past inhabitants. Their longevity of use and their relationships both with other monument types and with the islands' rising sea level provides valuable information on the developing settlement patterns, social organisation and farming practices throughout a considerable proportion of the islands' human occupation.

This hut circle south of The Brow survives substantially intact. Despite some superficial disturbance by wave action on the upper levels of its walling it clearly retains both its overall form and such details as its facing slabs, while the rubble trapped within the walling will protect the hut circle's buried internal features. Its survival well within the inter-tidal zone, despite rising sea levels, confirms its long term stability against a considerable period of submergence. The proximity of this hut circle to the prehistoric settlement remains in Green Bay and the east coast of Samson Hill, and to the cairn cemetery on the summit of Samson Hill, demonstrates the relationship between domestic, farming and funerary activities among the prehistoric communities that used this monument. It also complements those nearby prehistoric field system and settlement survivals at various levels around southern Bryher to provide an unusually complete view of prehistoric land use across the altitude range into the now-submerged zone.


The monument includes a prehistoric stone hut circle situated in the inter-tidal zone 60m south of a bulge in the coastline called The Brow on the south east coast of Bryher in the Isles of Scilly. The hut circle is defined with a sub-circular wall of heaped rubble, up to c.1m wide and 5.5m in external diameter, rising to 0.4m high. The wall and much of the interior is often festooned by seaweed but through this a series of edge-set outer facing slabs, up to 0.2m high, is visible intermittently; where least masked by the vegetation on the south, the facing slabs are closely spaced. Occasional edge-set inner facing slabs are also visible along the inner side of the wall. The hut circle interior is partly masked beneath a spread of rubble, distinguished from the wall rubble by its lower height and irregularly hollowed surface. The rubble of this spread has been dislodged from the wall's upper fabric by wave action and become trapped in the interior, covering and preserving the hut circle's internal deposits from the tidal flows. This hut circle is located 50m south west of a prehistoric enclosure and adjacent trackway, forming the southerly known exposure of an extensive area of prehistoric land division surviving in the inter-tidal zone of Green Bay, Bryher. Another hut circle is exposed in the cliff face on the eastern coast of Samson Hill, 75m south of this scheduling. The summit of Samson Hill, overlooking this scheduling from the south west, contains a cemetery of prehistoric cairns. The inter-tidal remains which include this scheduling bordering south eastern Bryher are complemented on the south west coast of Bryher by another prehistoric field system and settlement surviving in Great Porth and extending over the Heathy Hill promontory. The hut circle, prehistoric cairn cemetery, field system and settlement are the subjects of separate schedulings.
