History

Kilmacthomas is a town located on the River Mahon in County Waterford. During the Cromwellian Invasion in 1649, Oliver Cromwell marched from Waterford to Kilmacthomas during the Siege of Waterford. His army couldn't cross into the town as the river was flooded, so they spent two nights in the field that is now the public park.

The influence of the Industrial Revolution reached Kilmacthomas in the early 1870s. The stone viaduct carrying a railroad from Waterford to Mallow, extending across the Mahon River, is a prime example of this.
