The townland of Caltragh, in County Sligo, holds one such site, a rath, which is the Irish term for a ringfort built from earthen banks rather than stone. These enclosures, typically circular, were the farmsteads of early medieval Ireland, home to a family and their livestock, enclosed for both status and security. Most date from roughly the fifth to the twelfth centuries, and they appear in townland names, in folklore, and in the faint circular cropmarks that aerial photography has revealed across the country.

Caltragh itself is a townland whose name derives from the Irish "cealtrach", a word associated with a burial ground or a place of the dead, which lends the location a quietly layered quality. A ringfort sitting within such a townland sits at the intersection of two kinds of ancestral presence, the domestic and the funerary, both folded into the ordinary field patterns of the Sligo countryside. Beyond the monument type and its setting, the available record for this particular site is sparse, and to speculate further about its dimensions, condition, or history would be to move beyond what is actually known.
