The one at Rickardstown, in County Westmeath, is a different proposition. It has been almost entirely levelled, and what remains is less a monument than a memory pressed into the ground: a circular scarp no more than 0.4 metres high tracing an enclosure roughly 21 metres across. You would need to know what you were looking at.

A ringfort, sometimes called a rath, was typically a circular enclosure defined by one or more earthen banks and ditches, used as a defended farmstead during the early medieval period in Ireland. The Rickardstown example sits on the lower south-western face of a high ridge, a position that would have offered both some shelter and a degree of elevation. It appears on the 1837 Ordnance Survey Fair Plan map as a roughly circular enclosure, annotated simply as "fort", which suggests it was still recognisable as a distinct feature at that point. By the time aerial photography captured the site in November 2011, however, the picture was considerably bleaker. Along the southern, south-western, and western edges, the original rampart has been replaced by a modern field fence and trench, the boundary of someone's field now running over what was once the perimeter of an early medieval enclosure. The south-eastern arc of that perimeter has left no visible trace at all, and it is precisely at that gap that the original entrance is thought to have been located, the absence of an earthwork where a break in the bank would have been deliberately placed.
