An extensive building of various periods of construction, which is of national importance having originally been established as a cotton mill forming the centre of a planned ‘model’ industrial village founded by David Malcomson (n. d.). Subsequently converted to use as a spinning factory, and later a tannery, the site is of importance for having historically supported the economy of Portlaw – the tannery, in particular, reflects the protectionist policies of the Irish government following independence in 1922. Although in a dilapidated condition, features of technical or engineering interest survive intact, including some machinery and a water tower, together with the early construction in mass- and reinforced concrete. The complex remains an important, although increasingly obscured, landmark in the core of the village.
