Police CCTV images want to talk after graffiti was issued after the damage to Yorkshire's UNESCO World Heritage Site.
According to North Yorkshire police, Fountains Abbey near Ripon targeted approximately 23:30 GMT on Sunday.
Using oil-based white paint, he wrote that he “doesn't steal drugs” with medieval plaster on a building with Grade I listed, but caused “substantial” damage, police said. The graffiti had also been found at nearby St. Mary's Church, they added.
The Force spokesman asked him to contact him with anyone who recognized the man or with information about the incident.
