Historic graffiti at Lincoln Cathedral was recorded between January and June 2018 by the Lincolnshire Medieval Graffiti Project. The survey identified an exceptionally large number of historic marks, numbering in the thousands of examples. The marks are distributed throughout the cathedral, on almost every available surface, but do seem to have a concentration around the central crossing. The survey revealed an exceptionally large range of graffiti types were present, with examples of almost all of the main medieval and post-medieval graffit types being identified and recorded, along with many of the much rarer types present. Some of the more significant marks include at least 11 examples of ship graffiti, 26 examples of possible music notation, 24 human figure or face representations, and 9 merels and 6 other medieval gaming boards. {1}{2}
