These circular or polygonal towers, built to house pigeons on an industrial scale, were never part of the native Irish tradition; they arrived with the Anglo-Norman and later English planter classes, who valued the birds both as a reliable winter food source and as a marker of landed status. The one at Bushypark, on the outskirts of Galway city, belongs to that quiet category of estate structures that outlasted the houses they served, surviving in the landscape long after the social world that produced them has dissolved.

Beyond its association with the Bushypark area west of Galway city, the documentary record for this particular structure is thin. What can be said is that dovecotes of this type were typically estate dependencies, built to serve a nearby country house, and their presence usually indicates a property of some consequence. The pigeons kept inside, known as columba livia in their domesticated form, were housed in rows of small nesting boxes, called columbaria, cut or built into the interior walls. Access to the eggs and squabs, the young birds taken before fledging, would have been managed through a rotating ladder or potence fixed to a central post, allowing a single person to reach every nesting hole without disturbing the rest of the flock. That the Bushypark structure has persisted at all places it among a relatively small number of surviving Irish examples, most of which have lost their original fittings entirely.
