The site appears on Taylor’s 1783 map of County Kildare, marked as ‘Ca. Rs.’, though it vanished from later Ordnance Survey maps drawn in 1838 and 1939. Today, visitors would struggle to find any obvious signs of the structure that once stood here, but the field holds subtle clues to its past.

In 1985, surveyors discovered dressed stones scattered across the site, some still bearing traces of mortar, though the landowner explained these had been dumped there recently rather than being original to the castle. More intriguingly, they recorded low linear earthworks running north to south across the field, features that showed up clearly on aerial photographs taken in 1986. These earthworks have since disappeared from view, worn away by decades of farming and weather.

The most enduring evidence of the site’s history lies about 200 metres to the east, where traces of a fosse, or defensive ditch, mark what was likely an enclosure associated with the castle. These subtle depressions in the earth, first noted in 1985, remain the only visible reminder of the medieval settlement that once occupied this quiet corner of Kildare. While the castle itself has vanished without trace, its proximity to the surviving medieval church and graveyard suggests this was once an important local centre, now returned to farmland.
