Wedge tombs are the most numerous of Ireland's megalithic tomb forms, built during the late Neolithic and into the early Bronze Age, roughly between 2500 and 2000 BC. They take their name from their shape: a roofed stone gallery that narrows and lowers from one end to the other, typically oriented to face the setting sun in the west or south-west. They are, in the plainest sense, constructed places for the dead, though the rituals that accompanied their use have not survived in any written form.

Killanena parish lies in the barony of Tulla Upper, a stretch of country where limestone gives way to rougher, more elevated ground as it moves toward the Slieve Bernagh hills on the Clare and Tipperary border. This part of Clare has a quiet density of prehistoric remains, the kind of landscape where field boundaries, bog edges, and low ridgelines have preserved features that more intensively farmed ground elsewhere has long since swallowed. A wedge tomb in this setting would have been a significant communal monument in its time, marking territory, ancestry, or some relationship between a community and its dead that is now largely opaque to us.
