The mound, rectangular in form and measuring roughly 18 metres by 8 metres with a height of between one and a half and two metres, sits in a well-sheltered rock hollow beside a short stretch of river that behaves in a distinctly Burren fashion: it rises to the south-west, runs briefly above ground, then disappears into the karst beneath to the north-east. The hollow appears to have been chosen deliberately, offering shelter and a reliable, if brief, surface flow sufficient to drive a mill wheel.

The site appears on a 1977 map by Robinson, which marks it as the "site of mill (flax?)" with a question mark that quietly acknowledges how little is certain. Flax milling was once a common rural industry across Ireland, with mills used to ret and process the plant before spinning and weaving, though the presence of one this deep in the Burren is a detail worth pausing on. The mill sits within a multiperiod field system, meaning the landscape around it shows traces of human activity spanning several different eras, none of them easily pinned to a single date. Roughly 90 metres to the west stands a cashel, a type of stone-walled ringfort characteristic of early medieval Ireland, suggesting the area was organised and inhabited long before the mill was built or fell into ruin.
