Rosemarket Rath is an oval enclosure, about 130m east-west by 97m, set on a south-facing spur-end above a stream confluence, defined by double banks and ditches on the north-east, elsewhere by scarps above steep natural slopes; the north-east-facing entrance appears to have been recently reconfigured. A pipe trench dug across the north-east of the enclosure (Barnie 1975) provided a section through the defences. St Ismael's church lies immediately to the north, and the churchyard may partially overly the silted ditch of the enclosure ? suggestive of early medieval reuse as a cemetery, as known at a number of other Iron Age enclosure sites.
