Place & story

A Wednesday market

In 1837 Samuel Lewis described Ballyvary as a market town on the road from Castlebar to Swinford, near a small river flowing from Lough Cullen. Wednesday was market day, with fairs on 29 May,18 August and 14 November. A constabulary station served the town. Its Catholic chapel occupied a site supplied by the Reverend L. Rutledge of Bloomfield. These details show a settlement with regular commercial and administrative functions, drawing people from farms beyond the short village street. [2]

William Malley's mill

The three-storey mill was reconstructed by William Malley and was standing by 1859. Malley was bankrupted in 1862, but the building's industrial history continued: the architectural survey records it in use in 1945. Its surviving shell retains window openings framed in contrasting red or yellow brick. The roof has disappeared and ivy covers much of the masonry. The substantial building marks the scale of an enterprise which needed both storage space and a carefully managed water supply. [3]

Reading the millponds and the Castle Park field

Archaeological testing in 2009 examined ground south of the mill where local historical accounts had suggested a castle site. The apparent stony bank proved to contain burnt limestone associated with a small limekiln. The investigation also documented the mill's water-management landscape: ponds created after 1838, a massive dam wall and slots interpreted as controls for an older mill-race. The road to Balla, laid out in 1884, crossed the southern end of the dam. Water still overflowed along that route until around 1980, leaving traces of industrial use well beyond the mill walls. [4]
