Cademuir Hill Fort is a fortified place near Peebles, Scottish Borders, Scotland.

What follows is drawn from published sources, with each claim labelled by how firmly it is established.

The name

The name attaches to Cademuir Hill, the ridge between Manor Water and the Tweed near Peebles; the fort itself takes its name from the hill. A firm philological derivation is not established in the gathered sources, so the name is treated here as the local hill-name rather than given a confident meaning.

History

Two Iron Age forts crown the Cademuir ridge. The larger, Cademuir I, on the summit, enclosed about 2.25 ha within a single 3 m thick stone wall and held the traces of at least 35 timber-framed round-houses (identified by circular ground-grooves), with space for as many again — described by RCAHMS as effectively 'a small town' and a site 'of more than local significance' in the earlier Iron Age.

The smaller, lower fort on the western summit (NRHE 51281, Scheduled Monument SM2441) is one of only two forts in the district to incorporate a chevaux-de-frise into its defences. More than 100 earthfast stones still stand over a distance of nearly 80 m, set on the reverse slope of a shallow gully across the level north-east approach so that they would have been invisible to attackers until they had breasted the gully and were already among the stones.

Both forts appear to have been abandoned around AD 80, about the time of the Roman arrival in the area; the larger fort shows no stone-built houses or secondary structures, suggesting it was given up rather than reoccupied. The nearby Hamildean Hill fort was left unfinished, perhaps for the same reason.

Cultural influences

The chevaux-de-frise — a defensive field of upright stones designed to break up a charge of men or horses — is a rare feature in Britain. Cademuir is one of only two examples in its district (the other being Dreva Craig nearby), linking it to a small group of Iron Age forts that adopted this unusual obstacle.
The ridge sits astride a strategic Tweed Valley–Upper Clyde through-route whose flanks are 'peppered with fortified hilltop settlements' (e.g. White Meldon, Hamildean Hill, Whiteside Hill), placing Cademuir within a dense Iron Age fortified landscape of south-east Scotland.

Discovery & excavation

The forts were systematically recorded by RCAHMS (visited 1962; published in the 1967 Peeblesshire inventory) and re-surveyed by the Ordnance Survey in 1971. The smaller fort measures internally about 73 m by 36 m (0.23 ha) within a massive stone wall up to 6 m thick on the east flank; its interior, partly adapted into a sheepfold at the north end, retains the traces of ring-groove timber round-houses. The site was re-assessed for the Atlas of Hillforts of Britain and Ireland (record SC3653) in 2015–16.

What to look for

The chevaux-de-frise on the north-east approach of the smaller fort: more than 100 earthfast stones strung across the level ground beyond a shallow gully — the single most distinctive feature on the hill.
The massive ruined stone walls reduced to scree-like rubble on the flanks of the knoll; on the east flank the wall was up to 6 m thick, with stretches of both faces still visible in situ.
Circular 'ring-groove' marks in the turf of the interiors — the footprints of timber round-houses (35+ in the larger fort; a couple traceable in the smaller).
A later sheepfold built into the north end of the smaller fort's interior, overlying the prehistoric remains.

What is said

Folklore and tradition, recorded as what is said — not as established fact.

The line of 28 stones known locally as 'The Shearers', crossing the plateau near comparable Border forts, is said by some to be standing stones; archaeologists consider them more likely the 'grounders' of an ancient field-dyke. (This tradition is recorded for Hownam Rings; noted here only as the kind of 'standing-stone' folklore attached to such Border ridge sites — not specific to Cademuir.) (regarded by archaeologists as a field-dyke, not standing stones)
