Beneath the manicured front lawn of one of Ireland's grandest Palladian houses, a gas pipeline trench in 2010 cut through something considerably older than the Georgian stonework above it. Workers carrying out restoration for the Office of Public Works at Castletown House in County Kildare found themselves looking at a Bronze Age burial ground, roughly four and a half thousand years old, lying just below the surface of a lawn that generations of visitors had strolled across without any idea of what was underfoot.

Archaeologists opened an area of approximately eight by nine metres to investigate what the service trench had already partially destroyed. At the centre of the find was a crouched inhumation, the body having been placed in a contracted, foetal position, accompanied by a crushed ceramic vessel. Both the burial style and the pottery appear to belong to what archaeologists call the Bowl Tradition, a mode of Bronze Age burial associated with the later third millennium BC, in which the dead were interred individually in pits alongside carefully made round-bottomed bowls. The trench had also sliced through at least six further pit burials, each sub-circular in shape and between one and two metres across, their fills packed with cremated bone. Four additional sherds of prehistoric pottery were recovered. Taken together, the pits form what appears to be a small cemetery. A compact concentration of stony material about three metres in diameter, lying to the north-east of the excavated burial, may be the eroded remnant of a low focal mound, otherwise levelled over the centuries. The spatial arrangement is suggestive: the smaller pits containing cremations appear to have been inserted into the edges of this stony core, while the larger pits, including the one holding the inhumation, ring its outer edge. If that reading is correct, the site organised itself around a central monument, with different burial rites occupying different positions relative to it.
