It is modest in its dimensions, roughly three metres by three and a half metres, and what remains of it gives little away. The south wall survives to about a metre and a half in height, and set into it, at around chest height, is a small rectangular opening, just thirty centimetres tall and twenty wide. Whether that opening served a functional or defensive purpose is unclear, and the building's original use remains unrecorded.

What can be traced is the structure's long decline. The Ordnance Survey's six-inch map of 1841 already marks it as being in ruins, which places its abandonment well before the mid-nineteenth century at the latest. Local memory, however, holds that it still stood to roughly twelve feet before it was burnt sometime in the 1930s, a detail that suggests some portion of the walls remained intact far longer than the OS cartographers implied, or that their classification of 'ruin' was generous. A further collapse occurred more recently, and the overgrowth has since done considerable work in concealing what little stonework is left. The site was recorded by Denis Power and uploaded to the Historic Environment Viewer in August 2011, though the record is candid about how much remains unknown.

Moreena Point is not a destination with obvious infrastructure, and reaching the north-eastern corner of the peninsula requires navigating farmland on the Shannon's southern shore in County Limerick. The site itself is heavily overgrown, and the south wall, the most legible section of the structure, is the clearest thing to look for. The small rectangular opening in that wall, still visible despite the collapse, is the detail that rewards a closer look. Visiting in late winter or early spring, before vegetation thickens, is likely to give the clearest sense of the footprint and what survives of the masonry.
