Today, all that remains visible is a low mound stretching about 100 metres from east to west and measuring roughly 10 metres in width. The most distinctive feature is a central depression, which hints at the site's former structure; a single ring that would have defined this ancient enclosure, as recorded on the 2nd edition Ordnance Survey 6-inch map.

The site sits on grazing land, though thick vegetation has largely reclaimed the earthwork, making detailed examination challenging. This type of enclosure, common throughout Ireland, likely served multiple purposes throughout its history; from defensive farmstead to cattle enclosure, or perhaps as a ceremonial gathering place for the local community. The central depression may indicate where structures once stood within the protective ring, or it could be the result of later stone robbing or natural collapse over the centuries.

This description comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of archaeologists. Their work documented field antiquities across the county, spanning from the Mesolithic period through to the 17th century, creating an invaluable record of Donegal's archaeological heritage. Sites like this Roosky enclosure, whilst modest in their current appearance, form important pieces of the puzzle in understanding how our ancestors lived, worked, and defended their communities in rural Ireland.
