Summary

Collooney Mills is a protected industrial complex beside the Owenmore River whose statutory entry expressly includes associated buildings and the mill race.[1] The site embodies several phases of water-powered industry—linen, woollen, corn/flour milling and later hydroelectric generation—but much of the surviving mill fabric is now disused and visibly ruinous, while parts retain community or generating uses.[4][2]

Identification

Address: Bleachgreen, Collooney, Co. Sligo.[1]
Eircode: Unverified; an Eircode for the complex itself was not confirmed.
Building type(s): Industrial mill complex; corn/flour mill, earlier linen/woollen mill, water-management works, mill race and hydroelectric infrastructure.[4]
Approx. date of construction / period: Earlier milling activity is reported from the medieval period; the linen mill is attributed to c.1710–1720, the principal flour-mill complex to c.1830, and generating infrastructure to the 1890s (Medium; complex contains multiple phases).[4][3]
Architect / builder: Unverified. Alexander Sim is reported as the developer of the c.1830 complex, not necessarily its architect.[3]
RPS / NIAH / other heritage references: RPS 81 CDP. The RPS prints “3231005”; this should be checked against the NIAH dataset because it appears shorter than the normal eight-digit registration format.[1]
