Ringforts
In a pasture field on an east-facing slope in Co. Longford, a broad circular rise in the ground marks something that was already old enough to be labelled simply "Fort" when the Ordnance Survey mapped it in 1837.
What survives today is the earthwork shell of a rath, the Irish term for a ringfort, which was typically a farmstead of the early medieval period enclosed by one or more earthen banks. The bank here has been reduced over centuries of agricultural use, but the underlying form persists.
The site presents as a roughly circular raised platform, measuring approximately 31.5 metres north to south and around 30 metres east to west. Its edge is defined by a scarp, a steep drop in the ground surface, standing between 0.9 and 1.4 metres high in places. Beyond that scarp lies a wide, shallow fosse, that is, a surrounding ditch, roughly 6 metres across and between 0.6 and 0.9 metres deep, which remains legible along the southern, northern, and north-eastern arcs. The original entrance, which in many ringforts takes the form of a deliberate gap in the bank, is no longer identifiable here. That absence is not unusual; centuries of grazing, ground disturbance, and gradual silting can erase the subtler features of a site while the main earthwork endures.
The fosse is best observed from the southern and north-eastern sides, where erosion has been gentler. Because the site sits in working pasture, the grass cover actually helps reveal the form; low morning or evening light, which casts longer shadows across the scarp, tends to make the earthwork easier to read from a short distance.
