What remains is a low scarp, no more than 0.6 metres high, tracing the northern and eastern boundaries of what was once a deliberately enclosed space. The southern and western edges, where the enclosure would have closed in on itself, are now occupied by field walls and a laneway that have long since absorbed or erased whatever earthwork stood there.

The enclosure measures more than 47.6 metres on its west-north-west to east-south-east axis and over 13.7 metres north to south, making it a substantial feature even in its fragmentary state. Enclosures of this general type, defined by a bank, ditch, or scarp, were used across Ireland for a wide range of purposes over many centuries, from early medieval settlement and farming to later agricultural functions that are harder to pin down without excavation. The site at Pollnamal has not been dated with any precision, and its original purpose remains unknown. What is clear is that it was once a meaningful boundary in this landscape, and that roughly 100 metres to the south, a second earthwork occupied the same general area, suggesting this was not an isolated feature but part of a broader pattern of activity that has since grown quiet.
