Twenty-nine toghers, a togher being a timber trackway laid across boggy or waterlogged ground to allow passage, were identified in the Killoran townland during field survey, making this one of the more concentrated clusters of such features recorded in the Irish midlands. That so many should survive in a single townland speaks to both the density of early medieval movement through this landscape and the preserving qualities of the bog itself, where waterlogged, oxygen-poor conditions can hold organic material in extraordinary condition.

A survey carried out by Gowen in 1999 documented the construction methods in detail. Fifteen of the toghers were built from brushwood alone, while the remainder combined brushwood with roundwood in varying arrangements. Three examples showed evidence of pegs or stakes, suggesting a more deliberate effort to anchor the structure against shifting ground. Wood species were identified across thirteen of the toghers, with ash and hazel predominating, though alder, birch, elm, holly, and mountain ash were also present. This variety points to a practical use of whatever timber was locally available rather than any standardised selection. A radiocarbon date obtained from one togher placed its construction between AD 1024 and 1162, placing it firmly in the early medieval period, a time when Ireland's bogs were criss-crossed by routes connecting settlements, farms, and ecclesiastical sites that are now long gone or much altered.
