Today, nothing of it remains above ground, which makes the paper trail it left behind all the more quietly interesting.

The Civil Survey of 1654 to 1656, a Cromwellian-era land inventory compiled to establish ownership and value across Ireland following the wars of the 1640s, recorded the crossing as "a foord called Ballagurtcullan". It sat on a brook that formed the boundary, or "mearing", between the parishes of Ardagh and Druming in the barony of Moydow. By the time the Ordnance Survey revised its six-inch maps in 1913, the ford was still being noted, this time alongside a "F.S.", meaning a foot-stone, a single flat or upright stone set in the water to allow a person to cross without wetting their feet. The map placed it at the junction of the two parishes, which corresponds with the older description. Whether the 1913 cartographers were recording something still in use at that point, or simply acknowledging a feature that local knowledge had preserved, is not clear. Either way, the foot-stone and the ford itself have since vanished, leaving only the name Ballagurtcullan and its brief appearances in the historical record.
