That ambiguity is, in its own quiet way, the most interesting thing about it. The site is listed as a possible hut site, roughly eight metres in diameter, one of several thought to occupy the slope below the hillfort's enclosing wall. When the area was inspected in November 2012, this particular example could not be located at all.

The hut site was first recorded by a researcher named Grogan in 1989, as part of a broader survey of the area. It sits, or is thought to sit, within one of the more substantial prehistoric complexes in County Wicklow, the Spinans Hill hillfort system, of which the Brusselstown Hill hillfort forms a part. A hillfort is broadly what it sounds like: a defended enclosure, usually on elevated ground, defined by earthen banks, ditches, or in this case a stone rampart. The clustering of hut sites along the inner slope of such a structure is a pattern seen elsewhere in Irish prehistory, suggesting these were spaces of habitation as well as defence. Whether this particular hollow or platform in the ground ever amounted to a dwelling, though, remains unresolved. The landscape has a way of absorbing things.
