The Triple Dyke is a linear earthwork forming part of the Iron Age and Romano-British defences of Camulodunum, the major territorial oppidum established in Essex from the first century BC. The monument comprises three parallel banks and ditches that functioned as both boundary markers and defensive barriers, controlling access across the settlement's extensive landscape. Dating primarily to the late Iron Age and continuing in use during the Roman period, the Triple Dyke exemplifies the sophisticated territorial organisation characteristic of late pre-Roman British élite centres. The earthwork remains visible as substantial earthen ramparts in the landscape around modern Colchester, preserving evidence of one of Britain's most significant proto-urban settlements.
