That practical adjustment, unassuming as it sounds, is a small window into the careful thinking of early medieval Irish farmers and landholders who built these enclosures, known as raths or ringforts, across the Irish countryside in their thousands.

A rath is an enclosed farmstead, typically of the early medieval period, formed by one or more earthen banks with accompanying ditches. This example at An Ráth Thoir measures approximately 33 metres east to west and 31 metres north to south, making it a modest but solid specimen of the type. The defining bank stands about 1.5 metres above the interior and 1.1 metres above the exterior ground level on the eastern to northwestern arc, accompanied by a shallow external fosse, or ditch, roughly 0.3 metres deep. Where the bank gives way, a natural scarp takes over, rising to 2.6 metres, suggesting the builders worked the existing topography to their advantage rather than constructing everything from scratch. There are two breaks in the bank, one to the south-southwest at around 2 metres wide and another to the southwest, at least one of which likely served as the original entrance. Across the interior, faint traces of cultivation ridges run on a northeast-southwest axis, evidence that the enclosed space was used for growing crops at some point, whether during the rath's primary occupation or in a later phase of agricultural use.

The site sits in open pasture today, its banks grassed over and its fosse much reduced by centuries of weathering and land use. The cultivation ridges visible inside are the kind of detail easily missed without some prior knowledge of what to look for, presenting as gentle undulations in the turf rather than anything dramatic. The scarp on the southern side, at nearly two and a half metres, remains the most physically imposing feature and gives a clearer sense of how the original enclosure would have felt from the outside, a modest but deliberate boundary between the domestic world within and the open landscape beyond.
