The site features the grass-covered foundations of what was once a tower house, positioned at the northeast corner of a raised circular enclosure measuring roughly 36 metres north to south and 33.6 metres east to west. This elevated platform, standing 1.7 metres high with a possible entrance gap on its northern side, served as the castle’s bawn; a defensive courtyard typical of Irish tower houses.

The origins of this circular enclosure remain intriguingly uncertain. It may have begun life as an early medieval ringfort, or perhaps as an Anglo-Norman ringwork from the 12th or 13th centuries, before being repurposed as a bawn when the tower house was built. The visible grass-covered wall footings that trace the enclosure’s edge, now only 40 centimetres high, could represent this later defensive addition. Alternatively, the entire complex might have been constructed as a single ambitious project, with the enclosure and tower house conceived together as an integrated defensive system.

Adding to the site’s historical richness, the medieval ruins of Cahervally Church and its associated graveyard lie just 50 metres to the east-northeast. The landscape itself contributes to the defensive nature of the site, with quarried rock outcroppings immediately to the north and south providing natural barriers. These features, combined with the sweeping views across the Limerick countryside, made this an ideal location for a fortified residence, whether it served Anglo-Norman lords or Gaelic Irish chieftains during its centuries of use.
