The castle appears as a small, square building on the 1838 Ordnance Survey map, positioned just south of a laneway a few metres north-northwest of a farmyard. Interestingly, later revisions of the OS maps from the 6-inch and 25-inch editions incorrectly relocated the castle further west, demonstrating how even cartographic records can sometimes lead us astray when tracing Ireland’s lost heritage.

The site commanded an advantageous position above the lough to the southwest, typical of defensive structures that needed clear sightlines across the surrounding landscape. While the castle’s exact history remains elusive, its strategic placement suggests it likely served as a tower house or fortified dwelling, common throughout medieval Ireland for local landowners seeking both security and status.

Today, visitors to Raheen will find little evidence of the castle that once dominated this spot. The structure has been completely levelled, leaving only a few large stones breaking through the surface; possible remnants of the original foundations. These modest traces serve as a quiet reminder of how many of Ireland’s medieval buildings have vanished from the landscape, surviving only in old maps, archaeological surveys, and the occasional stone poking through a field.
