The site’s story begins in 1253 when Alan Prutfot held tenancy of nearby Dowth manor, though the castle itself likely wasn’t built until around 1461, when Richard Proudfoot found himself embroiled in a boundary dispute with the abbot of Mellifont. This medieval stronghold would go on to feature prominently in the Down Survey maps of 1656-8, marking its place in the complex web of land ownership that characterised 17th-century Ireland.

By 1640, the castle and its surrounding 130 acres had become jointly owned by Sir John Netterville of Dowth and Lord Charles Moore of Mellifont, though the Civil Survey of 1654-6 reveals that Lord Moore held exclusive ownership of the castle itself, along with a stone house, an orchard, and a corn mill. These structures formed part of a working agricultural complex that continued to function well into the 19th century, as evidenced by the 1836 Ordnance Survey maps which show the castle integrated into a farm setting.

What remained of Proudfootstown Castle gradually diminished over time; by 1908, the Ordnance Survey recorded only a small shell measuring roughly 4 metres by 3 metres, likely the remnants of a projecting stairs or garderobe tower. An 1890 description by Balfour noted the base of what appeared to be a circular tower, approximately 3.5 metres in diameter and standing just 1.8 metres high. Today, no visible trace of the castle survives, leaving only historical records and maps to tell the story of this once-significant fortification that played its part in the territorial disputes and changing fortunes of medieval and early modern Meath.
