Castle - ringwork, Rathealy, Co. Kilkenny
This circular earthwork, measuring approximately 42 metres north to south and 47 metres east to west, sits just below the ridge crest on reclaimed grassland. The monument’s strategic position between two parallel valleys would have provided excellent defensive advantages whilst offering panoramic vistas in all directions. A medieval church and graveyard lie just 60 metres to the southeast, suggesting this was once an important local centre.
The ringwork’s defences consist of multiple concentric earthworks that demonstrate sophisticated medieval engineering. The raised interior is surrounded by a broad bank standing up to a metre high internally and 4.5 metres externally, followed by a steep-sided, flat-bottomed fosse six metres wide. Beyond this lies an intervening bank, then an outer fosse and bank, though these outermost defences are only visible in the southern and southwestern sections. The main entrance, located in the eastern quadrant, is 1.9 metres wide and features what appears to be a square depression immediately inside on the southern side, possibly the remains of a guardhouse measuring roughly 4.5 by 4.3 metres.
Within the interior, archaeological surveys have identified the remains of four rectangular buildings, and historical accounts from Carrigan’s 1905 work mention an underground chamber or cave beneath these structures, possibly a souterrain typical of Irish medieval sites. Another pit, measuring three metres square and 0.7 metres deep, can be found near the bank in the southwestern quadrant. The site has been designated National Monument number 376, recognising its importance as one of Ireland’s significant medieval fortifications. Though a modern field boundary runs along the northern portion, carefully skirting around the monument and possibly incorporating some of the outermost bank, the ringwork remains remarkably well-preserved, offering visitors a tangible connection to medieval Ireland.
