Castle – tower house, Newcastle South, Co. Dublin

Just east of a bend in Athgoe Road in Newcastle South, County Dublin, lies an intriguing piece of medieval history that's now completely invisible to the casual observer.

Castle - tower house, Newcastle South, Co. Dublin

This spot marks the possible location of a tower house, one of three such structures that once stood in close proximity to each other in this area. While the other two tower houses remain visible landmarks, this particular site has been reduced to mere foundations beneath the surface.

The evidence for this lost tower house comes from archaeological surveys conducted in the 1980s, when researcher O’Keeffe documented the remains of mortared wall foundations on the level ground beside the road. These foundations suggest the structure was built using similar construction methods to other medieval tower houses in the region, which typically served as fortified residences for local gentry during the late medieval period. Tower houses were particularly common in Ireland from the 15th to 17th centuries, offering their inhabitants both security and status in an often turbulent landscape.

Today, visitors to the site won’t see any trace of these foundations at ground level; the remnants lie buried beneath the earth, their exact outline known only through archaeological documentation. The location’s proximity to two other tower houses hints at a once densely fortified local landscape, where noble families maintained defensive strongholds within sight of one another. This hidden site, compiled in records by Geraldine Stout, serves as a reminder that Ireland’s medieval heritage often lies just beneath our feet, waiting to tell its story through careful archaeological investigation.
