It is not a ruin in the conventional sense, nor a castle or abbey, but the working boundary of a seventeenth-century deer park, still legible in the land despite the centuries between its construction and now.

Deer parks were a feature of elite estate management from the medieval period onward, enclosed circuits of land where deer were kept for hunting and for the visible demonstration of wealth and status. This particular example in Wicklow was recorded on the first edition Ordnance Survey six-inch map, which places its presence firmly in the historical record by the mid-nineteenth century at the latest. A more detailed investigation was carried out in February 2000, when Johnston and Devane undertook a plan, elevation, and photographic survey of the north-western section of the boundary. What they documented was a wall built in mortared stone, constructed to revet, meaning to retain or face, a low earthen bank, with an internal ditch running alongside it. Together, the wall, bank, and ditch formed a barrier designed to keep animals in rather than intruders out. The surviving 285-metre stretch represents only part of what would originally have been a full circuit enclosing the park.
