Castleruddery is a stone circle dating back to the early Bronze Age. It is approximately 100 feet in diameter, and consists of 29 granite stones (out of an estimated original 40),some upright and some flattened. Two notable quartz boulders, each weighing approximately 15 tonnes, stand at the eastern side of the circle, marking what was probably the entrance.
The circle sits atop an artificial earth platform, which is ringed with an embankment. This, in turn, was once surrounded by a ditch (still visible in aerial views). Outside this ditch there was originally another earth embankment, making Castleruddery a rare example of a concentric-henged stone circle. Scattered stones to the east suggest that there may once have been an avenue approaching the stone circle.
Castleruddery is a very special site. It is clearly well cared for, with the farmer keeping the interior neatly mown to allow proper appreciation of the stones. The embankment creates a feeling of separation from the outside world, and the ambience is enhanced by the whitethorn trees that have sprung up around the circle - one of which nestles a stone within its roots.
The name Castleruddery comes from the Gaelic "Caisleán an Ridire", meaning "Castle of the Knight", and it is locally believed that the stone circle holds healing properties.
Castleruddery is definitely one of the finest stone circles in this part of Ireland, and a personal favourites out of those that I visited.
