Earthwork SE of Trelan Plantation is a scheduled monument situated in Cornwall, England, at grid reference SW 73544 19111. The site occupies 0.12 hectares and is protected by Historic England as scheduled monument number 1004379. The earthwork lies upon Devonian bedrock comprising an unnamed igneous intrusion of ultramafic character, reflecting the region's complex geology formed during the Devonian period some 360 million years ago.
The earthwork's form and function remain to be precisely determined through formal archaeological investigation, though its scheduled status confirms its recognised archaeological significance. The underlying geology of ultramafic igneous rock has shaped the landscape around Trelan Plantation, influencing both the monument's preservation and the broader settlement patterns of the area.
The designation as a scheduled monument ensures legal protection for this archaeological site, reflecting the importance of recording and understanding Cornwall's varied earthwork heritage. Such monuments contribute to understanding prehistoric and later settlement, land use and social organisation across the county.
