Halnaker Hill Causewayed Enclosure is a Neolithic monument located near Chichester in West Sussex, consisting of interrupted ditch circuits that enclosed an area used for gatherings, ritual activity, and possibly periodic settlement during the fourth millennium BC. The site is characterized by its distinctive segmented or causewayed ditch system, typical of early Neolithic communities across southern Britain, which allowed access across the enclosed space at regular intervals. Later occupation of the hilltop is evidenced by World War II searchlight emplacements and associated defensive structures, reflecting the site's strategic location during the 1940–1941 aerial campaign. These later military installations represent the palimpsest of human activity at this prominent landscape feature spanning nearly six thousand years of history.
