Built around 1830, this four-bay country house incorporates the remains of a much older medieval castle into its eastern elevation. The main house presents a refined Georgian appearance with its two storeys over basement design, central breakfront, and classical portico facing west. What makes it particularly intriguing is how the builders chose to preserve and integrate the late medieval castle ruins rather than demolish them, creating a unique marriage of defensive medieval architecture and elegant 19th-century domestic design.

The site has a long and complex history of ownership that reflects Ireland’s turbulent past. The Civil Survey of 1654-56 records that Walter and Morcas Leo, described as Irish Papists, owned the property which then included a castle, a bawn (a fortified enclosure typical of Irish plantation castles), and several houses. By 1840, when the Ordnance Survey documented the area, the property had passed to the Ievers family, with R. Ievers, Esq. residing in what was then called Castle Iever or Tullerboy House. The survey noted that the ruins of the ancient castle were still adjoining the main residence, suggesting the medieval structure was already partially ruined by that time.

The medieval castle remnants that survive today feature rubble limestone walls topped with cut limestone crenellations and a stringcourse running beneath them; classic elements of defensive architecture from Ireland’s castle-building era. The National Inventory of Architectural Heritage has recognised the significance of this unusual architectural ensemble, where centuries of Irish history literally share the same walls. The five-bay side elevation of the Georgian house and the medieval castle’s sturdy limestone construction create a striking visual narrative of how Ireland’s landed estates evolved from military strongholds to comfortable country residences whilst maintaining physical links to their martial past.
