These circular earthworks, typically defined by one or more raised banks and ditches, were the dominant form of rural settlement during the early medieval period, in use roughly between the fifth and twelfth centuries. Most were farmsteads, home to a single family and their livestock, though their earthen rims have long outlasted any trace of the timber or wattle structures that once stood inside them.

The ringfort at Tully takes its place in a county that is unusually well supplied with early medieval remains. Sligo's varied terrain of drumlins, limestone lowlands, and coastal margins made it attractive to farming communities across many centuries, and the density of surviving enclosures here reflects that long occupation. Beyond its location in Tully, the specific details of this particular site, its dimensions, its condition, whether it retains a visible bank or has been reduced by centuries of ploughing, remain undocumented in any publicly available form at present.
