Overview

History & significance

Clawdd-Mawr is a linear earthwork located in Carmarthenshire, Wales, dating to the Early Medieval period. The monument consists of a substantial bank and ditch system that served a defensive or territorial function during the post-Roman centuries when Welsh kingdoms were consolidating their power. Such linear earthworks were characteristic of Early Medieval Welsh settlement patterns and frontier demarcation, though the precise dating and original extent of Clawdd-Mawr remain subjects of archaeological study. The surviving earthwork demonstrates the engineering capability of Early Medieval Welsh communities and contributes to understanding settlement organisation and land division in medieval Carmarthenshire.
