This castle ringwork, a type of fortification popular in the 12th and 13th centuries, consists of a substantial circular mound measuring approximately 33 metres north to south and 35.5 metres east to west. The mound’s height varies considerably, ranging from 2.62 metres in the northeast quadrant to 4.19 metres in the southwest, creating a broad, flat-topped platform that once likely supported timber buildings and defensive structures.

The defensive features of this ringwork are particularly well-preserved. A fosse, or dry moat, measuring 3.8 metres wide encircles the central mound, whilst an outer bank provides an additional layer of protection. This outer earthwork varies in width from 1.8 to 6.3 metres at its crest, with the broadest sections reaching up to 10.6 metres in the northeast quadrant. The bank stands between 1.09 and 1.7 metres high depending on where it’s measured from, and in the southern sector, later field boundaries have been incorporated into the original structure. Here, you can still spot evidence of stone revetments on both the internal and external faces, suggesting efforts to reinforce and maintain the earthwork over time.

The interior of the mound slopes downward towards the east, where archaeologists believe the original entrance was positioned. Today, the monument supports a thriving ecosystem of lush grass, thistles, and nettles, with scrub vegetation clinging to its edges. The site forms part of a broader medieval landscape; a ringfort lies about 90 metres to the northwest, whilst two possibly conjoined enclosures can be found roughly 80 metres to the northeast, hinting at a complex pattern of settlement and defence in medieval Tipperary.
