The site known as Rabbit Burrow sits at the northern end of a ridge in gently undulating grassland in Barnpark, County Galway, and what lies beneath that modest, animal-world nickname is a ringfort of considerable age and substance. It is the kind of place that asks you to look twice.

The structure is a circular ringfort measuring 33.5 metres in diameter, defined by a bank and an intervening fosse, which is essentially a defensive ditch dug to complement the raised earthwork. Ringforts were the most common form of rural settlement in early medieval Ireland, typically serving as enclosed farmsteads for a single family or small community, and thousands survive across the country in varying states of preservation. This one is in fair condition. A causeway marking the original entrance survives at the east-south-east, and traces of a second, outer bank remain visible along the northern to east-north-eastern arc of the enclosure, suggesting the site may once have had a more complex arrangement of defences than is immediately apparent today. Quarrying, however, has eaten into the enclosing elements at the south-east, leaving that portion of the earthwork compromised.
