The Fosse at Verulamium is a substantial linear earthwork forming part of the defensive system of the Roman city of Verulamium, located near St Albans in Hertfordshire. Dating to the later first or early second century AD, the feature comprises a ditch and associated bank that functioned as a boundary and defensive work for the expanding settlement. The earthwork remains visible as a considerable topographical feature within the modern landscape, preserving evidence of Roman military engineering and town planning during the period when Verulamium was established as a significant urban centre in Roman Britain. The fosse represents an important survival from the formative phase of the city's development.
