A long and narrow hollow or trench dug in the ground, often used to carry water though it may be dry for much of the year.
Within this category you have the following sub-types:
- Practice Trench
- A system of trenches dug by troops for practice purposes.
- Ring Ditch
- Circular or near circular ditches, usually seen as cropmarks. Use the term where the function is unknown. Ring ditches may be the remains of ploughed out round barrows, round houses, or of modern features such as searchlight emplacements.
