Castle - ringwork, Shanbally, Co. Tipperary South
On a gently sloping ridge in the pasture lands of Shanbally, County Tipperary South, sits a curious triangular enclosure that locals have long known as 'Lonergan's Fort'.
Castle - ringwork, Shanbally, Co. Tipperary South
This medieval ringwork, measuring approximately 40 metres north to south and 42 metres east to west, is surrounded by a substantial stone bank that still commands attention despite centuries of weathering. The bank itself is an impressive construction; whilst its crest is just over a metre wide, its base spreads to nearly four metres, rising over two metres on the external face where it hasn’t been damaged by time and farming.
What makes this monument particularly striking is the deep fosse, or defensive ditch, that encircles it. At six metres wide and over two metres deep, this formidable barrier would have presented a serious obstacle to any unwanted visitors. The enclosure’s unusual triangular shape is most evident in its southern section, which runs in a straight line from east to west, whilst the northern portion forms a distinctive rounded point. Time hasn’t been entirely kind to the structure; the outer bank face shows erosion in places, particularly to the north and northeast, and a three-metre section has collapsed outward on the eastern side.
Whilst no obvious entrance survives, archaeologists have noted a low mound in the fosse on the southeastern side that might once have supported a bridge or even a drawbridge, suggesting this was a well-defended site in its day. The monument appears on historical maps from as early as 1937, when antiquarian Lyons suggested it might have originally served a sepulchral purpose, though its defensive features strongly suggest it functioned as a ringwork castle during the medieval period. Today, a substantial field boundary runs alongside the western and southern edges of the enclosure, a reminder that this ancient fortification continues to influence the modern landscape.
