On elevated rocky pasture in Ballymihil, County Clare, a subcircular drystone structure measuring roughly 28 metres north to south and 24 metres east to west sits in the landscape with that puzzle quietly unresolved. Drystone construction, meaning stone laid without mortar, is common across the west of Ireland, but the absence of any discernible entrance gap sets this one apart from the more obviously functional enclosures of the region.

The site sits within a broader field system and commands wide views eastward and northward across the surrounding terrain, suggesting that whoever built it had reasons, whether practical or otherwise, for choosing this particular elevated position. At the centre of the enclosure stands a house site, meaning the remnants of a former domestic structure, which adds a layer of complexity to the question of the enclosure's original purpose. A cashel, a type of stone ringfort typically associated with early medieval settlement and livestock management, lies approximately 80 metres to the north-east, hinting that this corner of Clare was once a good deal busier than its present quietness suggests. The enclosure was recorded on the six-inch Ordnance Survey map of 1916, confirming it was a recognised feature in the landscape at least by that date, and it was formally listed in the Record of Monuments and Places in 1996.
