This circular earthwork measures approximately 18.6 metres across from north to south and 19.5 metres from east to west internally. The site consists of an earthen platform that rises between 1.5 and 3.6 metres above the surrounding pastureland, encircled by a protective bank that stands anywhere from 30 centimetres to 1.3 metres in height.

The interior of the fort slopes gently towards the north-northeast, and whilst the site has seen recent agricultural use, its ancient form remains clearly visible. Ringforts like this one at Rahanlacky were once common throughout Ireland, serving as defended homesteads for prosperous farming families during the early medieval period, roughly from 500 to 1200 CE. These structures typically housed extended families along with their livestock, stores, and workshops, all protected within the circular enclosure.

The strategic positioning of this particular rath, commanding views across the river valley below, would have given its inhabitants both defensive advantages and control over the surrounding fertile grazing lands. Today, the site stands as a testament to Ireland’s rich archaeological heritage; one of thousands of similar earthworks that dot the landscape, each telling the story of communities that flourished here over a millennium ago.
