Monument record BUT 064 - World War I practice trenches, visible on aerial photographs as earthworks.

A military trench, probably dug for practice purposes, is visible on aerial photographs as a cropmark located to the east of Carmen's Wood, Butley parish, centred on circa TM384501. The main trench is laid out in a triangle roughly 60m to a side, while the trench itself is dug in a crenellated pattern. The crenellated form was intended to disperse the effects of an explosion in the event of a hit from enemy fire. A straight trench may lie on the outside edge of the triangle on the two eastern sides. Probable geological features and drainage trenches of a Post Medieval date may also be visible in this area as cropmarks but have not been recorded. (S1, S2)
