No earthworks break the surface, no walls catch the eye; the only trace of it in the landscape is a slight irregularity that careful survey work has managed to outline. What survives, essentially, is the memory of a boundary rather than the boundary itself.

The site appears on the 1839 edition of the Ordnance Survey six-inch map, labelled as the site of Fort Garrett, suggesting that even by the early nineteenth century the structure was already understood as a remnant rather than a functioning feature. The mapped outline describes a D-shaped enclosure, a form commonly associated with early medieval ringforts, running roughly 70 metres east to west and 60 metres north to south. A lane running east to west clips the southern edge, cutting into what would have been the full circuit of the enclosure. A castle has also been recorded at precisely the same location, pointing to a site that was reoccupied or built upon across different periods, with one layer of activity obscuring or overwriting another. The slight westward-facing slope on which it sits would have been a practical choice for any defended or enclosed settlement, offering drainage and a degree of natural visibility, though none of this translates into anything a visitor could now read from the ground.
