It looks, at a glance, like a boundary marker or a forgotten gatepost, but it is in fact a leacht cuimhne, a commemorative monument, raised to mark the precise spot where a man named Oliver Brown was thrown from his horse and killed in 1628.

The structure is built from mortared limestone, neatly finished and remarkably intact for something approaching four centuries old. Its base plinth extends to just over three metres at its widest, giving the pier a solid, intentional presence at the roadside. Early Ordnance Survey mapping, beginning with the first-edition six-inch sheets, recorded it simply as "Monument", a label carried forward into the 1:2500 survey of 1912 to 1916. By the revision surveyed between 1925 and 1931, it had acquired the more specific name "Laghta Oliver Brown", and the accompanying name book set down the tradition attached to it: that it was erected to commemorate Oliver Brown, killed at this spot in 1628. A plaque once fixed to the south face gave physical form to that memory, but it has since been removed. The rectangular recess where it sat is still visible, an absence that speaks to how monuments accumulate and then shed their inscriptions over time, leaving the stone itself as the only constant.
