Historical records from Westropp’s 1906-7 survey confirm their existence, though these structures apparently vanished by the early 19th century. The 1838 Ordnance Survey six-inch map marks a building annotated as ‘Tower’ which may have been one of these four castles, with one site indicated south-east of the churchyard and another to the north of the village.

According to the Urban Survey of County Limerick conducted by Bradley and colleagues in 1989, traces of these castles survived until the early 1800s before disappearing entirely. One castle may have occupied the site of what later became Caherconlish House, located south-west of the village, as noted by historian Lenihan in 1866. The fortified town houses would have served as defensive residences for prominent families, providing both security and status during the medieval period.

The historical landscape of Caherconlish also included a “college” mentioned in Lewis’s 1837 topographical dictionary, though its exact nature and location remain unclear. Today, visitors to the area will find no physical remains of these medieval structures; however, the Ordnance Survey maps and historical documentation compiled by researcher Caimin O’Brien in October 2018 help piece together the defensive architecture that once defined this Limerick town.
