This oval enclosure in the townland of Clonleame occupies a low rise in undulating pasture, with marshy ground spreading away to the south, south-west, and north-west. It was not formally identified until Edmond O'Donovan carried out fieldwork in 2021, though aerial images taken as far back as 2009 show its outline clearly enough once you know what to look for.

A ringfort, sometimes called a rath, was a circular or oval enclosed settlement typical of early medieval Ireland, roughly the fifth to twelfth centuries. The enclosure was usually defined by one or more earthen banks, known as a fosse and bank arrangement, and would have contained a farmstead or small homestead within. The Clonleame example measures approximately 62 metres north to south and 55 metres east to west. It was levelled at some point in the distant past, so the interior is now flat and unremarkable to the eye. The western side preserves the clearest surviving remnant of the original bank, a curving earthwork some 37 metres long, 7 metres wide, and roughly a metre high on its outer face. Around the rest of the circuit, the bank has been removed entirely, and the line of the enclosure can only be traced through an extremely shallow fosse, no more than 20 centimetres deep in places and about 5 metres across. On the south-east and eastern sides, faint traces of what appear to be relic field boundaries suggest that the landscape immediately surrounding the fort was once organised in some deliberate way. A second ringfort lies about 900 metres to the north, making this a quietly populated corner of early medieval Westmeath, even if almost nothing of it now breaks the surface.
