Today, little remains of the medieval fortress beyond a scattered pile of stones and a single displaced piece of masonry, but the site tells a far richer story through its surrounding landscape. The castle’s location appears on the 1913 Ordnance Survey map as a circular mound, marked simply as ‘Castle (Site of)’, a testament to its long abandonment.

What makes Croughal particularly intriguing is the complex network of earthworks that spreads out from the castle site into the neighbouring fields. These scarps and embankments, likely connected to the castle’s original defensive system or associated settlement, create a subtle but extensive archaeological footprint across the pastoral landscape. The full scale of these features wasn’t fully appreciated until aerial photography captured them in 1969, revealing patterns and structures that are difficult to discern from ground level.

Modern satellite imagery continues to show these earthworks clearly, offering visitors and researchers alike a chance to trace the outline of what was once a significant fortification. While the stone structure itself has largely vanished, claimed by time and possibly repurposed by local builders over the centuries, the earth itself preserves the memory of Croughal Castle’s former prominence in this quiet corner of County Westmeath.
