Castle, Porterstown, Co. Westmeath
Porterstown Castle in County Westmeath stands as a fragmentary reminder of Ireland's medieval past, now awkwardly incorporated into a farmyard that dates from after 1700.
Castle, Porterstown, Co. Westmeath
The castle sits on a gentle natural rise, and whilst early Ordnance Survey maps from 1837 show it as an L-shaped freestanding structure just south of a small garden plot, by 1910 it had already fallen into ruin. The 1655 Down Survey map reveals its strategic importance, depicting the castle alongside a medieval road that connected Mullingar to Dublin, a vital thoroughfare in its day.
Today, only two sections of the castle walls remain standing, both in poor condition and heavily weathered. The western wall fragment stretches about 2 metres in length and rises to roughly 3.5 metres, its 1.1 metre thick walls now covered in ivy with no visible architectural features. A smaller section of the northern wall survives at about 1 metre long and 2 metres high, similarly featureless. Grass-covered footings trace out where walls once stood; one runs about 8 metres west from the castle’s southwest angle before turning northwest for another 9 metres, where it’s been incorporated into a field fence. The southeastern angle may also contain original wall footings beneath a field fence, though certainty is impossible given the structure’s deteriorated state.
The castle’s history is tied to the turbulent politics of 17th century Ireland. In 1640, the lands belonged to Thomas Darcy, recorded as an Irish papist in contemporary documents. Following the Irish Confederate Wars of 1641 to 1653, Darcy’s lands were forfeited and granted to Captain Robert Cooke and Ensign George Eaton, part of the massive transfer of land ownership that reshaped Ireland after the conflict. The surviving ruins, though modest, offer a tangible connection to this contested landscape where medieval fortifications once guarded important routes and where ownership could change dramatically with the fortunes of war.
