Anotations

Scope note:

Formations made of earth, resulting from the grading, trenching, or embanking of earth for utilitarian or cermonial purposes. Examples include Medieval fortifications and ancient ceremonial sites in Britain and Europe. For earth constructions having more of an artistic, rather than functional, purpose, use "earthworks (sculpture)." For works considered architecture rather than engineering works, prefer "earthen architecture."
