English Heritage is trialling the use of visible body-worn cameras on its staff at four locations in an attempt to discourage antisocial behaviour and crime.
Used at Wrest Park in Bedfordshire, Tilbury Fort in Essex, Kenwood House in north London and Marble Hill in south London, English Heritage says that footage is being recorded "on the basis of our legitimate interest in deterring and detecting crime".
"Experience of these cameras has shown that they are useful at helping defuse confrontational situations and provide a reliable version of events, which can help us to clarify any dispute or serve as evidence in the event it is believed a crime has been committed."
The move follows the recent publication of research commissioned by Historic England and the National Police Chiefs' Council that examined heritage and cultural property crime in England.
The report highlighted problems, including the theft of historic lead and stone, burglaries targeting cultural objects, unlawful metal detecting, and the removal of artefacts from protected wreck sites. It also found issues with antisocial behaviour, including arson, vandalism, and graffiti, recommending a "more effective prevention and active enforcement of heritage crime".
