At Sraduff in County Tipperary, a water mill once stood in a state of ruin, documented on the Ordnance Survey six-inch map of 1843, and has since vanished so completely that no visible remains can be found at all. What survives is only the cartographic ghost: a label on a map, marking something already broken, already fading, at the moment it was first formally noticed.

The 1843 Ordnance Survey mapping of Ireland was a landmark project in itself, producing extraordinarily detailed records of the rural landscape at a time when that landscape was on the cusp of catastrophic change. The fact that the Sraduff mill was recorded as a ruin even then suggests it had already fallen out of use well before the mid-nineteenth century, perhaps in the decades of agricultural disruption and shifting milling technologies that preceded the Famine. Water mills of this kind were typically small, locally operated structures built to grind grain for nearby communities, dependent on a reliable stream and the continued investment of whoever held the land. When that investment stopped, the mills deteriorated quickly, their stone repurposed, their timbers rotted, the millrace silted over and absorbed back into the surrounding ground.
