D. 1836." The detail that catches the eye is not the building's abandonment, nor even its age, but that phrase, voluntary subscriptions. This was not a state institution, at least not at the outset. Local money built it, before the machinery of the Poor Law had fully taken hold in Ireland, and before the catastrophe that would make fever hospitals grimly essential.

The structure itself is two storeys, gable-ended, running roughly 21 metres east to west, and built from roughly coursed limestone blocks. The entrance front faces south-west and carries three bays, stone-arched window openings with sash windows, and a round-headed door with a fanlight above it, modest classical gestures that were fairly standard for civic and institutional buildings of the 1830s. Single-storey lean-to wings extend from each gable end, their front parapets giving the building a slightly more formal outline than its plain fabric might otherwise suggest. The ground floor was divided into four rooms arranged off a central hall and staircase, a layout that follows the practical logic of ward separation. A small two-storey outhouse to the south-east is known locally as the laundry house, which makes sense for any institution that had to manage infectious disease, and two toilet blocks remain attached to the south-west gable. The building was already recorded on the Ordnance Survey's six-inch map of 1842, and it appears to have functioned until it was superseded, sometime in the mid-nineteenth century, by a new fever hospital built alongside the Mallow Union Workhouse. That shift placed fever care firmly within the Poor Law system, a transition that reflected how Irish public health provision was being reorganised, and then almost immediately overwhelmed, in the years before and during the Famine.
