What makes this particular rath quietly interesting is the way two very different periods of land use have become physically entangled: the ancient enclosure and a comparatively modern field boundary have merged at the northern edge, where a later field wall runs east to west directly over the rath's bank. The older structure was simply absorbed into the working landscape rather than demolished or avoided.

A rath is a roughly circular earthen enclosure, typically built during the early medieval period as a farmstead or defended homestead, and this one at Anneville follows that general form. It is subcircular in plan, with internal dimensions of roughly 27.8 metres east to west and 26.3 metres north to south, sitting on a slight west-facing slope. What sets it apart from a straightforward earthen bank is the presence of a double-faced stone wall, between one and two metres wide and up to a metre high, built along the top of that bank. Stone wall collapse is spread across the bank beneath it, suggesting the wall has been deteriorating for some time. The western side has been worn down to little more than an external scarp. The enclosure appeared on Ordnance Survey six-inch maps in both 1842 and 1920, which confirms it was a recognisable feature in the landscape across those decades, though by 1996 it was catalogued simply as an 'Enclosure' in the Record of Monuments and Places, a national inventory of archaeological sites.

The site sits in ordinary working farmland, tree-covered and unassuming, its most visible feature perhaps the way the field wall to the north seems to ignore the boundary between ancient monument and agricultural convenience, crossing the rath's edge as though the two were always part of the same design.
