Castle, Farnagh, Co. Westmeath
What remains today is a rather modest rectangular structure, its western wall still standing at about five metres high, though the other three walls have long since crumbled away. The castle appears on historical Ordnance Survey maps from the 19th century, first depicted in 1837 as a rectangular building and later annotated as ‘Castle (in Ruins)’ on the 1910 edition.
The castle’s history stretches back to at least 1539, when it first appears in written records. According to the antiquarian John O’Donovan, who surveyed the area in 1837, these ruins belonged to the O’Melaghlins, one of the prominent Gaelic families of the region. The castle later passed through various hands; it was decreed to Lord Dillon in 1663 and eventually sold to Robert Mulock in 1748. The structure itself is built from large, roughly hewn blocks of conglomerate and limestone, with no dressed stone visible in what remains. A notable feature is a splayed window reveal in the western wall, created by a large breach in the lower central area.
Today, visitors to the site will find little more than that solitary western wall, measuring ten metres long and just over a metre thick. The masonry, whilst impressive in its use of large local stone, shows no signs of the finer architectural details one might expect from a more elaborate fortification. The castle stands about 135 metres from a nearby enclosure, and whilst the earthworks that might once have surrounded it have vanished, the linear structure remains visible from aerial photography, a ghostly reminder of Westmeath’s turbulent medieval past.
