The castle ruins, measuring approximately 6.65 metres by 4.8 metres with walls nearly 1.8 metres thick, rise to about 10.6 metres in height and retain their first stone arch. When surveyed in the nineteenth century, the building was already noted as appearing very old and completely covered in ivy. Just to the west, the mill race of the Old Mill runs past the castle, with the mill building itself located 355 metres to the south, whilst a moated site can be found 210 metres to the north-northeast.

The castle has a colourful history stretching back to at least the sixteenth century. In 1583, it was held by J. Roe Lacye, though records also mention Richard Mac Thomas Reylie as holder of Bodestick Castle and mill when he joined the Desmond Rebellion. Reylie had mortgaged the property for forty milch cows and their calves to J. Creagh. The early seventeenth century saw the castle change hands multiple times; in 1611, Robert Cullum granted it to H. Billingsley, an alderman of London, who subsequently passed it to James Golde.

The castle witnessed dark times during the 1641 Rebellion when W. Cullum of Bodestow, accompanied by soldiers, allegedly half-hanged E. Harding before throwing him into the River Deel. Following the Cromwellian period, in 1655 the lands of Woodstocke and Cahyreenossa were granted to W. Cullum, and later in 1668, confirmed to J. Odell during the Act of Settlement. Today, this ivy-clad tower house remains as a testament to centuries of turbulent Irish history, standing quietly amongst the woodlands that have grown up around it.
