It went unrecorded in cartographic terms for generations, occupying a gentle hillside with open views to the south and west, until aerial photography finally caught up with what the ground had been quietly holding all along.

The enclosure came to official attention through the Bruff aerial photographic survey of 1986, when it was catalogued as Bruff 132 (AP 4/3633). A circular embanked enclosure, with an external diameter of approximately 30 metres, it belongs to a type of monument found widely across Ireland. Embanked enclosures of this kind are generally understood as enclosed settlement sites, defined by a raised earthen bank around a roughly circular interior, though the specific date and function of any individual example typically requires ground-level investigation to determine. What makes the Wonderhill site particularly interesting is its relationship to the wider landscape: it sits roughly 380 metres north-east of a second enclosure (recorded separately as LI023-237----), suggesting this part of Limerick may have supported more activity in earlier centuries than the blank historic maps would imply. Compiled by Edmond O'Donovan and uploaded to the record in August 2020, the site was confirmed as a surviving above-ground monument through Google Earth orthoimages taken in March 2017 and June 2018.

The enclosure lies around 390 metres east of the townland boundary with Galboola, in what is currently pasture land, so access would depend on landowner permission. It is not signposted and there is no formal visitor infrastructure. Those with an interest in early settlement patterns would do well to consult the OSi orthoimages from 2005 to 2012, as well as the more recent Google Earth captures, before visiting, since the earthwork reads more clearly from above than it might at ground level in long grass. The south-facing slope means that low winter light, when vegetation is sparse, tends to throw earthwork features into the sharpest relief.
