A freestanding circular-plan dovecote or columbarium, rebuilt c. 1850, incorporating fabric of an earlier structure, the building possibly dates from the mid fourteenth century

Its function was to house pigeons, which would provide food for the monks in the abbey. Typical in form of such functional structures, its circular design incorporates an opening in the roof through which birds could enter, while the internal walls are lined with niches providing nesting space. Retaining much of its original form, this dovecote serves as a reminder of husbandry methods once widespread across Ireland.
