Rather than standing as ruins in the landscape, the castle’s stones were repurposed in the late 19th or early 20th century to build what is now Home Farm. This practical recycling of building materials was common practice in rural Ireland, where good quality cut stone was too valuable to leave unused.

The original castle site lies just south of the current house, though little remains visible above ground today. Local historian Davies visited the site in 1948 and believed he had identified a standing portion of the original castle structure. However, more recent archaeological assessment by Wilsdon in 2010 suggests this was likely a misidentification, given that the farmhouse itself had already been standing for at least a century by that point.

This transformation from medieval stronghold to working farmhouse tells a broader story about Ireland’s changing landscape. As the need for defensive structures diminished and agriculture became the primary concern of landowners, many castles across the country met similar fates; their stones quarried to build more practical dwellings, barns, and boundary walls. At Keelagh, the castle lives on in the very walls of Home Farm, a tangible link between the medieval and modern histories of this quiet corner of Cavan.
