The ringfort here is not immediately dramatic; it sits atop a low rise in the landscape, its circular platform slightly saucer-shaped rather than flat, and its enclosing bank just under two metres high. But that combination of an interior souterrain, the ancient network of cultivation ridges still visible across the ground, and a southeast entrance that may have been in use since the early medieval period gives the site an unusual density of detail for something so unassuming from a distance.

Ringforts, known in Irish as raths when built primarily of earth, were the dominant farmstead type in early medieval Ireland, roughly between the fifth and twelfth centuries. Thousands survive across the country in varying states of preservation. The Shandrum More example measures roughly 29.5 metres north to south and 32 metres east to west, enclosed by a scarp with a slight internal lip and a shallow external fosse, which is essentially a ditch dug to reinforce the boundary and make the bank appear taller from outside. Three breaks interrupt the outer bank, to the north-north-east, west, and south-east; the south-east gap is the widest at two metres and lines up with a gently sloping ramp leading down to the surrounding field. The possibility that this ramp is original, rather than a later agricultural intrusion, is what catches the attention. The souterrain in the north-west quadrant adds further interest; these underground passages, usually constructed from dry-stone walling and corbelled roofing, are found in association with ringforts across Ireland and are thought to have served variously as storage spaces, refuges, or ventilation structures for adjacent buildings. The cultivation ridges running on a north-south axis across the interior speak to later agricultural use of the enclosed ground, layers of activity accumulating quietly in the soil over centuries.
