Today, only the faintest traces can be spotted from aerial photographs; cropmarks in a field just south of where the railway line now cuts through what were once the castle’s foundations. When historian Westropp documented the site in 1906/7, he noted that the railway had already crossed through the castle’s base, leaving little more than a site marker in the landscape between Gotoon and Castlefield.

The history of this castle is somewhat murky, as Westropp suggested it might be the same structure known as Milltown Castle. Records from 1583 mention that one W. f. Ric. f. Edm. David MacGibbon, also known as MacDavid Nynnagh, held both the castle and mill of Milltown near Kilmallock before being killed at Cloghdalton during Sir John of Desmond’s rebellion. By 1655, the site had deteriorated into what contemporary documents describe as an ‘old ruinous Castle’, accompanied by the seats of two grist mills and a tucking mill, all under the ownership of William Creagh, an Irish Catholic landowner.

The 1659 Civil Survey of Limerick confirms Creagh’s ownership of these ruins, whilst the Down Survey map from 1654;6 shows two townlands called Milltown in Ballingaddy parish, with Millmount annotated as ‘Miltowne’, though curiously no castle or mill sites were depicted. By 1840, when the Ordnance Survey Name Books were compiled for Ballingaddy parish, surveyors could find only the site where the castle once stood. Today, with the River Loobagh flowing just 80 metres to the east, this pastureland holds little evidence of its medieval past, save for those ghostly cropmarks visible from above, marking where this once significant fortification commanded the landscape.
