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, the police said “don't steal drugs” with medieval plaster on buildings listed with Grade I, causing “substantial” damage. 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.
North Yorkshire Police Sergeant Danny Copperwhaight previously described vandalism as “a gruesome act of vandalism in a world-famous heritage.”
Fountains Abbey is one of two UNESCO World Heritage sites in Yorkshire, the other being Saltaire near Bradford.
The monastery's ruins are the largest in the country, dating back to 1132, when 32 monks left St. Mary's monastery in York and established a new community.
The monastery was disbanded by King Henry VIII in 1539, and the crown sold the property to the merchant, Sir Richard Gresham, before the crown was eventually handed over to the state trust.
