Wedge tombs, so called because the burial chamber narrows and lowers from front to back, are the most numerous of Ireland's megalithic tomb types and are particularly concentrated in the west of the country, with Clare among the counties that preserves a notable share of them.

The Knockalassa tomb is recorded in the foundational survey of Clare's megalithic monuments compiled by Ruaidhrí de Valera and Seán Ó Nualláin, published by the Stationery Office in Dublin in 1961. That volume, the first in a multi-county series, systematically documented the megalithic tombs of Clare at a time when many such monuments had received little formal scholarly attention. De Valera in particular was instrumental in defining the wedge tomb as a distinct category within Irish prehistory, separating it from the broader and somewhat loose classification of "gallery graves" that earlier antiquarians had used. The Knockalassa example forms part of that wider Clare inventory, a county whose varied limestone and upland landscapes sheltered communities who left behind an unusually dense concentration of these communal burial structures.
