At Mountfox in County Limerick, a roughly circular hollow sitting in pasture has attracted enough cartographic attention over the decades to prompt a formal record, only to be assessed, with a certain quiet deflation, as probably the waterlogged remains of a post-1700 quarry rather than anything of archaeological significance. It is the kind of place that rewards a particular type of curiosity, one less interested in antiquity than in how ordinary industrial activity leaves traces that outlast the people who made them.

The site sits around 60 metres east of a recorded enclosure and does not appear at all on the Ordnance Survey's first edition six-inch map of 1840, which is itself informative. Its absence from that early survey suggests it came into being sometime after that date, consistent with the assessment that it is a post-1700 working. By the time the 25-inch Ordnance Survey map was produced in 1897, it had been recorded as an irregular-shaped area measuring roughly 58 metres on its northwest to southeast axis and 47 metres on the northeast to southwest, with the surveyors noting it might indicate a small pond. A field wall running northwest to southeast clips its southern edge. Later mapping, including the Cassini edition of the six-inch series, shows a sub-circular depression of around 48 metres in diameter, with a second, smaller depression immediately to the south measuring approximately 36 metres east to west and 12 metres north to south. By the time aerial photographs were taken in October 2002 and orthophotos captured between 2005 and 2012, the feature had become defined less by its earthwork edges than by the scrub vegetation growing around its perimeter, which is how it continues to read on satellite imagery.

For anyone who finds themselves in this part of Limerick, the site is not signposted and carries no particular visitor infrastructure; it is agricultural land, and access would require permission from the landowner. The most legible version of the feature is arguably from above, where the ring of scrub marking its outline shows clearly on aerial and satellite imagery. On the ground, what a visitor would find is a low, irregular depression in pasture, probably holding water for much of the year given its evolution into a pond feature. A nearby enclosure to the west, recorded in the archaeological inventory under the reference LI039-111, is the more formally recognised site in the immediate area and might offer context for the broader landscape if that is what you are after.
