The site itself bears no visible traces today, but its proximity to other medieval structures tells a fascinating story of Ireland’s layered history. Just 60 metres to the west-southwest stands a medieval church and graveyard, built on what may have been an Early Christian site, suggesting this area has been significant for centuries.

The castle’s fate was recorded in the Ordnance Survey Letters of 1837, which noted that “a few years ago an old Castle stood near the Round Tower, but it has been thrown down; the stones of it are yet to be seen”. Interestingly, what the survey referred to as a ‘Round Tower’ was actually the tower of the medieval church, a common misidentification in historical records of the period. By the time this observation was made, the castle had already been demolished, leaving only scattered stones as evidence of its existence.

Today, whilst no surface traces of the castle remain visible, the site continues to intrigue historians and archaeologists. The proximity of multiple medieval and potentially Early Christian structures in such a small area suggests Killashee was once a significant ecclesiastical and defensive centre. The surviving church tower, graveyard, and the documented presence of the now vanished castle paint a picture of a once thriving medieval settlement that played an important role in the local landscape for generations.
