The site is not marked by standing walls or dramatic ruins but by something quieter: a series of low linear earthworks, the kind easily mistaken for natural undulation until you look closely and begin to trace the geometry of small rectangular enclosures, the ghost-plan of plots and boundaries that once organised daily life.

The earthworks sit on flat grassland at the foot of a west-facing hillslope, with a stream running north to south along their edge, and open views stretching north, south, and west. What makes Erry unusual is the density of associated remains clustered in one place. Alongside the settlement earthworks lie a church and graveyard, a castle with a bawn (a bawn being the walled or embanked enclosure that typically surrounded an Irish tower house for defence and livestock), and the remains of a watermill. To the east of the church, cultivation ridges survive within what appear to have been small fields, and these may be contemporary with the medieval occupation. Together, this cluster of features suggests a functioning rural community, one organised around its church, protected by its castle, and sustained by its mill and cultivated ground. There is no clear hollow way, the sunken track that often marks a village street worn down by centuries of foot and cart traffic, and no obvious house platforms survive, so the precise layout of the settlement itself remains uncertain. The earthworks visible today most likely represent property boundaries and enclosures rather than the footprints of buildings.

The site is best approached with an eye for subtle ground-level changes. The enclosure plots are most legible to the west of the church and graveyard, where the low ridges and ditches hold their shape in the grassland. The higher ground to the east, and the stream to the side, help orient a visitor trying to read the landscape as a whole rather than as isolated fragments.
