What appears to be a slightly raised patch of ground is in fact a rath, the Irish term for a ringfort, a form of enclosed farmstead built throughout Ireland during the early medieval period, roughly between the fifth and twelfth centuries. Thousands survive across the country, but each one carries its own particular geometry, its own relationship with the land around it.

This example at Carhoovauler measures 32 metres across in both directions, making it a reasonably substantial specimen. It is enclosed by an earthen bank standing 2.6 metres high, which would originally have served as a defensive boundary around a family farmstead, protecting livestock and inhabitants alike. Outside the bank runs a fosse, a defensive ditch, now partially silted up to a depth of around 0.6 metres, though it would once have been considerably deeper and more formidable. The most legible feature of the site is a gap 2.5 metres wide in the north-western section of the bank, the original entrance, complete with a causeway crossing the fosse. That a causeway survives at all gives the entrance a particular clarity; you can stand at that gap and understand immediately how the place once worked, how people and animals passed in and out of a life organised within this circle of earth.
