Banks are earthwork mounds that are longer in plan than width and usually act as a monumental boundary.






Banks vary in form and composition; they can be built in earth, stone, turf and rubble and they range in size from low and short to several meters high and kilometres long. They are often found in association with other monument types, particularly ditches but also walls or other earthworks that can be enclosed within or associated with the bank.
If a more specific form or function cannot be assigned, the monument is best identified by the shape of its course: see curvilinear earthwork and linear earthwork.
