Overview

History & significance

House Platforms West of Dyffryn Wood is a medieval domestic settlement site comprising earthwork platforms where timber-framed or stone buildings once stood. Located in Wales on geology of the South Wales Upper Coal Measures Formation, the site demonstrates typical settlement patterns of the medieval period when communities occupied upland or marginal ground across the Welsh landscape. The underlying bedrock of mudstone, siltstone and sandstone provided the physical foundation for construction, whilst the ironstone and coal deposits in the surrounding strata reflect the industrial potential of the broader region, though the settlement itself would have relied primarily on pastoral or mixed farming.

The house platforms are visible as levelled terraces cut into the sloping ground, a common building technique where inhabitants adapted the hillside to create level surfaces suitable for domestic occupation. Such platforms required significant labour to construct, indicating organised community effort and permanence of settlement. The individual platforms would have accommodated separate households, suggesting a nucleated settlement structure rather than isolated farmsteads.

The site is protected by Cadw, the Welsh heritage organisation, under reference GM549, recognising its importance to understanding medieval Welsh settlement patterns and land use. Excavation and surface survey of such sites have contributed considerably to knowledge of domestic life, building practices and economic organisation in medieval Wales, though detailed archaeological investigation of this particular location remains limited.
