What survives is a roughly rectangular earthen bank, measuring about thirty metres from north to south and twenty-five metres from east to west, accompanied by an external fosse, the term for the ditch dug alongside a bank to heighten its defensive or boundary effect. The bank itself survives along the northern, eastern, and southern sides; elsewhere the ground simply drops away in a natural-looking scarp that completes the circuit. At the north-east corner, a causewayed entrance gap just over two and a half metres wide marks where people once passed in and out, the causeway being the uncut strip of earth left across the fosse to allow access.

Enclosures of this kind are scattered across the Irish landscape in considerable numbers, and their purposes varied widely, from farmsteads and settlement enclosures to ecclesiastical or ceremonial spaces. The name Abbeygormacan carries a hint of ecclesiastical association, the abbey element suggesting a monastic connection somewhere in the locality, though the enclosure itself is described simply as a secular earthwork. It sits in a part of Galway where the land rolls gently rather than dramatically, the kind of countryside where such earthworks can survive for centuries in pasture, slowly softening into the grass until only careful survey work picks them out. The condition here is noted as poor, meaning the bank has been worn or disturbed to some degree, and the fosse is only clearly legible along its northern and eastern stretches.
