The classification alone tells you something is there, traced at some point by someone who thought it worth marking on the record. Beyond that, the details remain, for now, out of reach.

Enclosures of this kind are among the most common monument types in the Irish landscape. A ringfort, to take the most familiar example, is typically a circular or oval area enclosed by one or more earthen banks and ditches, used as a farmstead or defended homestead, most commonly during the early medieval period between roughly 500 and 1000 AD. Cashels follow the same basic idea but use stone rather than earth. They turn up in almost every county, often surviving as low, grassy rings in fields, easy to miss unless you know to look. The townland of Drummin sits in a part of Mayo with its own layered past, and an enclosure here would not be unusual in itself. What is unusual is how little can currently be said about this particular one.
