On Mullamast Hill in County Kildare, a plough broke through the earth in 1889 and struck something that had been sealed away for millennia. What it uncovered was a cist, a small stone-lined box burial, measuring roughly 76 centimetres long, 46 centimetres wide, and 61 centimetres deep. Inside lay cremated bone, the reduced remains of a person placed there during prehistory and left undisturbed through centuries of farming until that single season of cultivation brought everything to the surface.

The cist had been set within one of the barrows on Mullamast Hill, a barrow being a burial mound raised from earth or stone, typically during the Bronze Age, as a monument over the dead. The particular mound in question was ploughed out entirely in 1889, which is how the cist came to light. At those dimensions it is a modest structure, just large enough to contain the gathered bones of a cremation, and its discovery fits a pattern common across Irish hilltop sites where prehistoric communities chose elevated ground for their burial monuments. Mullamast Hill itself carries other associations, most notably as the site of a later early medieval inauguration place connected to the Uí Dúnlainge kings of Leinster, which gives the hill a long and layered history of significance extending well beyond this single find.
