The rath at Glenbeg in County Cork is one such survivor: a roughly circular enclosure sitting on a south-facing slope, its bank of earth and stone still standing to about one and a half metres, quietly holding its shape in the middle of ordinary pasture.

A rath, or ringfort, is the most common monument type in Ireland, the remains of a defended farmstead typically associated with the early medieval period, roughly the fifth to the twelfth century. They were working homesteads rather than military fortifications, the bank and ditch serving as much to keep livestock in as to keep threats out. This particular example measures approximately 23.5 metres east to west and 21 metres north to south, making it a modest but complete specimen. The bank retains a gap to the west-southwest, possibly an original feature or the result of later disturbance, while the main entrance faces southeast, a common orientation that would have caught morning light and offered a view down the slope.
