This is a rath, the Irish term for a ringfort, the most common class of monument in the Irish landscape. Thousands were built, mostly between roughly the sixth and tenth centuries, as enclosed farmsteads for a single family and their livestock. What makes each one quietly absorbing is how much of the original intention can still be read in the ground, more than a thousand years later.

This particular example takes an oval form, measuring just over forty metres on its longer north-west to south-east axis and roughly thirty-seven metres across. It is defined by a substantial earthen bank, outside which runs a wide, shallow fosse, a defensive ditch that in places remains partly waterlogged, suggesting the ground here holds water readily. The fosse would originally have reinforced the bank, with the excavated soil piled inward to increase the height of the enclosure wall. On the western side, a break in the bank marks what is almost certainly the original entrance, the point through which people, animals, and the ordinary business of early medieval life would have passed daily.
