The name Oliver's Battery refers to a prominent Iron Age earthwork. A fine Anglo-Saxon bowl from a burial within the Battery was on show for many years at the British Museum, but has now been returned to Winchester City Museum on long-term loan. The parish also contains a number of Bronze Age burial mounds. The Olivers Battery name dates back to the English Civil War and is specifically associated with Oliver Cromwell's siege of Winchester in 1645. A map of 1780 refers to the area as "Cromwell's Camp" and later maps show it as "Oliver Cromwell's Battery". The ancient earthwork may well have provided a suitable campsite for the besieging Parliamentarian forces, but cannon of the period would have lacked the range to fire on Winchester Castle and city walls from the so-called battery site.
