Today masons’ marks are often either ignored or thought to be of little importance while archaeological building surveys are undertaken. Some are noted and recorded as being present. However, by systematically recording the locations of all marks they can help identify different building phases of a structure like a castle, church or cathedral, especially in buildings which were constructed over several centuries. They can also add information on payment methods for the construction of the building. Moira Greig is the originator and leader of the Mason’s Mark Project, which to date has recorded marks on 75 buildings in Scotland, with 3 further in the pipeline. Moira was Archaeologist in the Local Government areas of Aberdeenshire, Moray & Angus for over 20 years, where she worked with local community groups on a number of projects, including this present project. Although retired from Local Government she continues to be heavily involved in Archaeology.
