Ringforts
At Carrickavallan in County Louth, a ringfort survives in a state that rewards careful attention precisely because it has been so thoroughly absorbed into the working landscape around it.
A ringfort, or rath, is a roughly circular or oval enclosure built during the early medieval period, typically as a farmstead or defended homestead, defined by one or more earthen banks and ditches. Here, the enclosing bank has been so reduced over centuries of agricultural activity that it is now almost flush with the interior ground level, its original profile softened beyond easy recognition.
The enclosure is oval in plan, measuring approximately 58 metres on its north-east to south-west axis and 41.5 metres across. The earthen bank, where it survives, reaches about 1.8 metres in height on the external face and around 5 metres in width, though it has been nearly levelled on the interior side. A possible entrance gap of roughly 2 metres sits at the west-north-west. What makes this site particularly telling is the presence of drystone masonry facing on the outer face of the bank, a detail that suggests the structure was not simply abandoned but was actively incorporated into the modern field boundary system. In effect, whoever laid out the surrounding fields found it convenient to use the ancient bank as a ready-made boundary, reinforcing it with stone rather than clearing it away. The fosse, the ditch that would originally have run outside the bank, has left no trace above ground. The interior has been further disturbed by cultivation ridges, the parallel earthworks left by ridge-and-furrow farming, which have cut across whatever archaeological deposits might once have been legible at the surface.
The site is a useful illustration of how early medieval remains and post-medieval farming practices can become so entangled that separating one from the other becomes genuinely difficult. The drystone facing, in particular, is the kind of detail that only becomes visible on close inspection, easy to read as simply a field wall unless the broader oval shape of the enclosure prompts a second look.
