This one at Lisdarush is anything but. Measuring eleven metres across and just under a metre in height, the circular mound dips slightly at its centre rather than rising to a peak, giving it a subtly hollow quality that sets it apart from the standard profile of a burial mound. It faces north-westward into a fold of the slope, the lake visible in the distance below.

A mound barrow of this kind is a prehistoric funerary monument, typically raised over a burial or as a marker of ritual significance, and was constructed during the Bronze Age or earlier. What makes the Lisdarush example particularly interesting is its immediate surroundings. Within roughly ninety metres to the south lies a ceremonial enclosure, a defined area set apart for ritual or communal purpose, and about thirty-five metres to the east sits a ring-barrow, a low circular bank enclosing a central area, itself another form of prehistoric funerary monument. The clustering of these three features in close proximity suggests that this corner of County Leitrim was a place of repeated and deliberate ceremonial activity rather than an isolated burial site. Such groupings are known elsewhere in Ireland, where prehistoric communities returned to established landscapes of the dead over generations, layering meaning onto particular stretches of ground.
