You can walk across it without any sense that the ground beneath your feet once marked the boundary of an enclosed farmstead, probably occupied during the early medieval period. The only way to see it at all is from above.

Ringforts, known in Irish as raths when defined by earthen banks and ditches, were the most common form of rural settlement in early medieval Ireland, built and occupied roughly between the fifth and twelfth centuries. What survives at Tinnock is the ghost of one: a circular feature picked out on vertical aerial photographs by what appears to be a single fosse, the term for the encircling ditch that would originally have accompanied an earthen bank. At ground level, under pasture, nothing registers. The site only becomes legible through the aerial archive, where subtle variations in crop growth or soil moisture can reveal buried features that centuries of farming have otherwise erased from the surface.
