Oval in plan and roughly 29 metres by 34 metres, it is the kind of place that can be hard to read at first: an overgrown interior sloping southward, a poorly preserved bank of earth and stone marking part of its edge, and a scatter of grave-markers, many of them now fallen flat. Those still upright are aligned roughly north to south. What makes the site particularly arresting is a structure at its centre.

This is the leacht from which the place takes its name. A leacht, in the Irish tradition, is a low rectangular cairn or altar-like structure, often associated with devotional practice at holy sites or burial grounds, and sometimes marking a venerated grave. Here, it is built of coursed drystone masonry, meaning stones laid in deliberate horizontal layers without mortar, with a notably large quantity of quartz stones worked through the fabric. Quartz appears with some regularity at Irish prehistoric and early medieval burial and ritual sites, and its presence here, gleaming pale against the darker stonework, gives the structure a quietly deliberate quality. The leacht measures 3.2 metres north to south and 2.45 metres east to west. About 1.2 metres to its south-east sits an irregular mound of loose stones, and further into the south-east quadrant, near the edge of the site, lies a large prostrate slab measuring 1.6 metres long, 0.4 metres wide, and 0.35 metres thick.

Burial grounds of this kind, sometimes called cillíní or cilliní, were used across Ireland for centuries to inter unbaptised infants and others considered ineligible for consecrated church ground. They occupy a liminal space in the landscape and in cultural memory, neither fully sacred nor fully secular by the standards of the Church, yet clearly tended with care by the communities who used them. At Ceann Eich, the site abuts a field boundary to the west and sits in rough pasture, its southern aspect open to the estuary below.
