The site appears on both the 1841 and 1906 Ordnance Survey six-inch maps, testament to its former significance in the local landscape. Today, however, visitors would struggle to identify any visible traces of the medieval fortification that once stood here.

Archaeological surveys have revealed faint evidence of the castle’s defensive features, including traces of a fosse, or dry moat, measuring approximately six metres wide along the western, northern, and northeastern sides of the site. These earthwork remnants offer the only tangible clues to the castle’s original footprint and design. The structure itself was destroyed roughly a decade before the archaeological inventory was compiled in 1995, erasing centuries of built heritage from the physical landscape.

The loss of New Castle represents a common fate for many of Ireland’s lesser-known medieval sites, where time, weather, and human activity have gradually eroded once-prominent landmarks. Whilst the castle no longer stands, its documented presence on historical maps ensures its place in the archaeological record of County Laois, serving as a reminder of the dense network of fortifications that once dotted the Irish countryside during the medieval period.
