Built for Colonel John Eyre, who was granted the lands following the Cromwellian conquest, Eyrecourt Castle was an early country house built on a symmetrical plan. It is one of the key houses of Irish architectural history, being one of the earliest undefended proper country houses. The surviving detailing of the building is superb, including remains of moulded timber window frames and elaborate scroll brackets to the eaves. Although ruinous for over a century, and blocked from view by later farm buildings, the remains of the house nonetheless form an important group with the entrance gates and the ruined chapel in the grounds.
