Just north of where Ballynadrimna House once stood, a solitary wall rises from the level landscape, its rounded corners and impressive thickness of 1.3 metres hinting at its defensive past. This surviving eastern wall, stretching nearly seven metres in length, still shows the springing point where a vault once arched from its inner face, a testament to the solid construction methods of its era.

The site’s documented history reaches back to at least 1640, when Lucas Dillon held 316 acres here in Kildalkey parish. According to the Civil Survey conducted between 1654 and 1656, Dillon’s property at Ballnedromne included both a castle and a mill, suggesting this was once a thriving agricultural and defensive complex. Curiously though, no castle appears on the Down Survey barony map of Lune, nor on any edition of the Ordnance Survey six-inch maps, leaving historians to piece together the site’s story from physical remains and written records.

Today, visitors to this overlooked corner of Meath can still trace the outline of what was likely a tower house or small castle, its surviving wall standing as a lonely sentinel over fields that once buzzed with the activity of mill wheels and estate workers. The structure’s robust construction, particularly evident in the remaining vault supports, speaks to the wealth and status of the Dillon family during a period when such fortified residences were both homes and statements of power in the Irish countryside.
