Wheathampstead earthwork is a late Iron Age settlement consisting of two concentric defensive banks and ditches enclosing an area on the chalk uplands of Hertfordshire. The site, known locally as the Devils Dyke and the Slad, dates to the 1st century BC and is interpreted as a major oppidum or fortified settlement of the Trinovantes or Catuvellauni tribes. The earthwork demonstrates substantial engineering effort with the inner rampart rising prominently and outer defences creating a formidable barrier, suggesting a settlement of considerable importance in the pre-Roman Iron Age. The site's strategic location and scale indicate it functioned as a significant tribal centre during the final centuries before the Roman conquest of Britain.
