During excavations carried out under the reference 97E0083, archaeologist Brendán Ó Riordáin uncovered a burial pit at Templerainy, designated Site L, containing the remains of cremated human bones. The pit sits within a wider funerary landscape: adjacent burial pits at the same site yielded Beaker and Bronze Age pottery, suggesting this corner of Wicklow was used repeatedly, across generations, as a place for the dead.

Beaker pottery takes its name from the distinctive vessel shape associated with a culture that spread across much of Europe from around 2800 BC onwards, and its presence here places at least some of the burial activity at the cusp of the Bronze Age in Ireland. Cremation was a common funerary practice during this period; the bones of the dead were burned, the remains gathered, and interred in pits, sometimes accompanied by ceramic vessels. The clustering of multiple burial pits at Templerainy points to a site that held significance over a considerable stretch of time, though whether the cremation pit excavated as Site L belongs to the Beaker horizon or a later phase of Bronze Age use is not recorded. Ó Riordáin's findings were published in 1999, as part of the broader reporting on the road scheme excavations.
