That such a feature exists here is not surprising given the property's history, but the specific nature of it remains tantalisingly undetailed in surviving records.

Clonbrock was the seat of the Dillon family, later the Barons Clonbrock, who held the estate for several centuries and were among the more culturally engaged of Connacht's landed families. The demesne gained particular distinction in the nineteenth century through the photography of Augusta Dillon, whose careful documentary work captured the estate's grounds, household, and tenantry in exceptional detail. Designed landscapes of this kind were typically laid out in the eighteenth or early nineteenth century, often by improving landlords keen to remodel their surroundings along the naturalistic lines then fashionable in Britain and Ireland, moving away from formal geometric gardens toward more apparently spontaneous arrangements of trees, water, and contoured ground.
