Hollow House on site of Castle, Ballynasrah Or Tinnycross, Co. Offaly
What remains today is a Georgian farmhouse, now hollow and abandoned, sitting within the footprint of a 17th-century castle complex. The castle itself has long since vanished, but its defensive bawn wall and four circular corner towers still stand as testament to a more turbulent time. These towers, punctuated with gun loops, were strategically designed to provide flanking fire along all four walls of the rectangular enclosure; a typical feature of plantation fortifications built during the Ulster Plantation period when English and Scottish settlers required defended homesteads.
The site tells a story of adaptation and reuse that spans centuries. When the original castle was demolished, likely by the very people who built the farmhouse that replaced it, they incorporated the existing bawn wall into their new dwelling, using it as the back wall of their cottage. This practical recycling of stonework was common practice in rural Ireland, where good building material was too valuable to waste. The gateway that now provides access to the site appears to be a later addition, dating from the late 18th or early 19th century, recognisable by its round arch topped with a triangular pediment and distinctive spiral finials; architectural flourishes that would have been fashionable during the Georgian period.
Today, both the farmhouse and the earlier fortifications stand empty, creating an evocative ruin where multiple layers of Irish history overlap. The gun loops that once protected Protestant settlers now look out over peaceful fields, whilst the Georgian gateway, built in more settled times, frames a view of structures that span over 400 years of continuous occupation and abandonment. It’s a quietly fascinating spot that encapsulates the changing fortunes and architectural pragmatism of rural Irish life.
