The structure is a stone-built domed icehouse, its interior lined with buff brick and open at the very top of the dome through a circular aperture, a design intended to regulate temperature and draw cold air downward. A rubble stone porch projects from the north side, and to the northeast the collapsed remains of what may have been a rectangular entrance passage or outer chamber can still be made out on the ground.

Dating to around 1820, the icehouse served Kinturk House, which stands roughly 265 metres to the northeast. Icehouses of this kind were a standard feature of prosperous Georgian and Regency estates across Ireland and Britain. Ice, harvested from frozen ponds during winter, was packed into the chamber and insulated by the surrounding earth mound and brick lining, allowing it to survive well into warmer months and supply the house with a luxury ingredient for chilled desserts and the preservation of meat and fish. The Kinturk example sits behind the former farmyard buildings of the house and close to its former walled garden, positioning it within what would once have been a busy working landscape of food production and storage. It is now disused and overgrown with vegetation, the porch partially obscured and the outer chamber reduced to rubble.
