A set of ancient burial sites near Brighton is the subject of a promise of increased police patrols after a report of criminal damage.
Sussex Police said that the Bronze Age bowl barrows at Hollingbury had been named in information given to officers.
According to data from Historic England, the site on the open space between Hollingbury and Moulsecoomb has been dated to the Early Iron Age (1200–550 BCE), and contains remnants of three bowl barrows and part of a hill fort, dated to the early sixth century BCE, though evidence remains of an earlier set of constructions.
Barrows are generally burial mounds, and the name 'bowl' is given to some of them because they resemble an upturned bowl.
They are most often found on hilltops.
The barrows near Hollingbury, evidence states, are near the centre of the hill fort's remains.
Excavations had occurred earlier in history, because evidence remains of a central hollow on each barrow where explorers would have dug.
One of the barrows, the most southern, could have been the site of a beacon during Mediaeval times and just afterwards.
Sussex Police's heritage crimes specialist officer PC Daryl Holter said officers would welcome reports of further damage or suspicious behaviour.
