In the pastureland outside Bansha, County Limerick, a ringfort once occupied a west-facing slope just below the brow of a hill. A ringfort, or rath, is a type of circular enclosure bounded by an earthen bank and ditch, built predominantly during the early medieval period and used as a defended farmstead. This one was modest in scale, approximately twenty metres in diameter, and it made it onto the 1841 Ordnance Survey six-inch map, which means it was still legible in the landscape when that meticulous Victorian survey was carried out. Sometime after that, it was levelled.

When surveyor Denis Power inspected the site, uploaded to record in August 2011, there was no visible trace of the monument remaining. The enclosure that had once been drawn with care onto the OS map had been absorbed entirely into the surrounding pasture. The site had also been cut by a passage leading to a garden centre to the south-east, and a new dwelling house stood roughly forty metres to the north-west. These are the ordinary pressures of land use across two centuries, agricultural improvement, development, and gradual attrition, and this ringfort is far from unique in having succumbed to them. Ireland once had tens of thousands of such enclosures; a significant number have vanished in exactly this way.

For anyone who makes the trip, it is worth being clear-eyed about what they will find, which is essentially nothing on the ground. The value here is less about what is visible and more about the act of reading a landscape against its historical record. The 1841 OS six-inch maps are freely available online through the OSi historical map viewer, and comparing that sheet with the current terrain can give a sense of what has been lost. The slope itself, on the western face of the hill, would have offered decent views and reasonable drainage, both practical considerations for whoever chose to build there. The garden centre access road that now cuts the site is an inadvertently useful landmark for locating the approximate position.
