That compression is what makes it worth pausing over.

The mill was designed by R. Brash and built in 1866 for the partnership of Wallis and Pollock, constructed on concrete foundations at a time when such a choice was still relatively uncommon in Irish industrial building. The ten-bay brick facade encloses a structure whose floors are formed by segmental jack arches, a technique in which small brick vaults span between cast-iron girders, distributing load and resisting fire in a way that simple timber floors could not. Four tiers of cast-iron girders carry this matrix throughout the building. Power came from an Inglis Corliss engine housed in a two-storey engine and boiler house attached to the eastern end, with gabled brick offices alongside. The mill closed in 1885, a closure that might have been permanent, but it reopened in 1890 after being refitted for woollen production rather than flax spinning. Then, in 1919, fire caused enough damage to require the roof to be replaced entirely, adding another layer to the building's already complicated history. A long single-storey range extends to the west, and the whole complex has since been absorbed into an industrial estate, which means the shell and much of the fabric survive, quietly, amid thoroughly unremarkable surroundings.
