In response to a surge in graffiti attacks on historic sites over the past year, Historic England is spearheading an innovative initiative to employ artificial intelligence (AI) as a potent tool against vandals targeting churches, castles, and monasteries. The groundbreaking project aims to leverage AI to identify culprits through their distinctive tags, track their movements across different areas, and analyze the paint used in the graffiti to determine the source of their spray cans.The urgency of curbing vandalism is underscored by a recent crime survey by Ecclesiastical Insurance, which reveals that heritage organizations have become a prime target. According to the survey, a staggering 32% of heritage sites have fallen victim to graffiti, marking a worrisome 9% increase from the previous year.

The defacement extends to iconic landmarks like Linlithgow Palace in West Lothian and Rochester Castle in Kent, where vandals have left their mark on historical walls, floors, and structures.Mark Harrison, Head of Heritage Crime Strategy at Historic England, emphasized the gravity of the situation, stating that graffiti in these heritage settings affects public well-being and community sentiment. Collaborating with Professor Robin Bryant, an AI expert and Director of Criminal Justice Practice at Canterbury Christ Church University, the project explores the potential of AI not only in identifying graffiti artists but also in combating other heritage crimes, such as the theft of lead from church roofs.The AI initiative holds promise in linking offenses to the same offenders, providing law enforcement with a valuable investigative tool.

Harrison suggests that by utilizing AI to identify the specific characteristics of graffiti, authorities can enhance their ability to apprehend vandals, dissuading further incidents. Additionally, the project considers AI's role in identifying stolen lead, offering a multifaceted approach to safeguarding heritage sites.Despite the challenges posed by the leaching nature of paint on ancient stone and the recurring nature of graffiti, Historic England remains optimistic. Harrison envisions a combination of traditional community measures and cutting-edge technologies, such as AI, as a glimmer of hope in protecting and preserving our shared cultural heritage. As the fight against heritage vandalism enters a new era, the integration of AI could prove instrumental in safeguarding these irreplaceable treasures.
