Set into undulating pasture on a north-facing slope in Ballycullane, County Limerick, this oval ringfort sits close enough to a second, catalogued ringfort immediately to its east that the two are thought to have originally been conjoined, a paired arrangement that was far from standard and suggests a more complex pattern of early medieval settlement than the surrounding farmland now implies.

A ringfort, or rath, is the most common type of early medieval enclosure in Ireland, typically a circular or oval area defined by one or more earthen banks and ditches, used as a farmstead and homestead from roughly the fifth to the twelfth centuries. This example at Ballycullane was recorded and compiled by Denis Power, with notes uploaded in August 2011. The enclosure itself is oval, measuring approximately nineteen metres north to south and fifteen metres east to west. Its most substantial feature is a scarped, that is, a steeply cut, edge running from the north-east around to the south-east, reaching a height of five metres and a width of fourteen metres, which gives the site a pronounced physical presence on the slope. An earthen bank follows the remainder of the circuit, with an external fosse, or ditch, running from the south around to the north-east. The bank has not survived intact; a modern east-west field boundary has truncated it along the south-eastern to southern arc, one of the more common ways in which these features are gradually worn away by agricultural reorganisation over the centuries.

The interior is level and grassed over for the most part, though a slight depression inside the bank along the south-western arc has collected enough moisture to support a growth of rushes, which can serve as a useful locating detail when approaching the site. Because the fort sits on a north-facing slope within working pasture, the ground underfoot can be soft, particularly after wet weather, and there is no formal access or signage. The adjacent ringfort to the east, recorded separately under the reference LI017-030, sits just beyond the field boundary and is worth examining alongside this one for any sense of how the two enclosures may once have related to each other spatially.
