No flowers remain, no paths, no ornamental planting; only the bones of the landscape itself, shaped into two conjoined rectangular enclosures connected by a well-defined causeway. The western enclosure runs roughly 170 metres north to south and 63 metres east to west; the eastern one is somewhat smaller at 105 by 67 metres. The scale alone suggests deliberate, ambitious design rather than agricultural use.

The garden, if that is what it was, belonged to an O'Byrne castle whose foundations were recorded by Liam Price in 1933. The O'Byrnes were a Gaelic lordly family long associated with County Wicklow, and the castle, which dates to the 17th century, stood on the eastern side of the larger enclosure, with a circular tower at its north-east corner. Price's description places the castle and the terraced ground in relation to each other in a way that suggests the enclosure may have served as the formal garden of the castle complex. That combination, a Gaelic Irish lord commissioning or inheriting a formal garden layout, points to the complicated cultural borrowings of the early seventeenth century, when elements of formal English and continental garden design were beginning to appear alongside, or within, Gaelic strongholds. The castle itself has since been reduced to foundations, and no above-ground trace of any garden feature survives.

What remains is the earthwork alone, sitting in open pasture with long views out over the valley. The terracing is clear enough to read as a landscape, even without its original function visible on the surface. The causeway linking the two enclosures is particularly well-defined, which gives the site a structural legibility that rewards a careful walk around its perimeter.
