The name of the townland itself is the most substantial clue available, carrying within it the Irish element "lacht", which typically refers to a burial monument or commemorative cairn, combined with what appears to be a personal name, MacDurkan. That combination suggests a place that was once considered significant enough to be named after a specific individual's memorial, though the connection between the name and the enclosure itself remains unclear.

Enclosures of this kind in the Irish archaeological landscape can take many forms, from the circular earthen banks of a ringfort, which served as a defended farmstead in the early medieval period, to earlier prehistoric enclosures whose functions ranged from settlement to ritual. Without further detail, it is not possible to say which category this particular site belongs to, or what period it dates from. What can be said is that the townland name points to a landscape with a long memory, one in which the marking of the dead and the naming of places after notable figures were intertwined practices that persisted in local usage long after the original monuments were raised.
