Kilmacthomas

During the Cromwellian conquest of Ireland, in December 1649, Oliver Cromwell, marched from Waterford to Kilmacthomas during the Siege of Waterford. The weather was wet and stormy and the river was in flood, so the army couldn't cross. Two nights were spent in the field that is now the public park. Cromwell was said to have described Waterford county on his march from Waterford to Kilmacthomas in the winter of 1649 as being a craggy and desolate place.

Daniel O'Connell passed through Kilmac' on a campaign trail and he wrote:[3]

We breakfasted at Kilmacthomas, a town belonging to the Beresfords but the people belong to us. They came out to meet us with green boughs and such shouting you can have no idea of. I harangued them from the window of the inn, and we had a good deal of laughing at the bloody Beresfords. Judge what the popular feeling must be when in this, a Beresford town, every man their tenant, we had such a reception.

In the early 1870s the influence of the industrial revolution reached Kilmacthomas when the Waterford to Mallow railroad came to town. There is an example of a stone viaduct in the town spanning the Mahon River. Although the last passenger services ceased in the late 1960s the railway continued to operate with the haulage of oil and magnesite for another couple of decades. This railway is now disused. The viaduct at Kilmacthomas has been preserved, and is part of the Waterford Greenway, which opened in 2017.

The town has a population of 1768. The chief tourist attraction of the locality are the Mahon Falls.

The village is situated on the River Mahon, the eastbank is known as Kilmacthomas and the westbank as Gruaigeshuneen (Gráig Sheoinín). The postal area of Kilmacthomas can include Newtown (Baile Nua), Ballylaneen (Baile Uí Fhlaithnín) , Lemybrien (Léim Uí Bhriain), Kill (An Chill), Mahon Bridge (Droichead na Machan), The Nire (Gleann na hUidhre), and Kilrossanty (Cill Rosanta). The N25 bridge over the River Mahon is named after local sporting hero Percy Kirwan.

The Mahon River has a stock of wild brown trout. The salmon run mostly in the autumn and winter, but start running from the end of June. Salmon trout (know locally as "Pale") are also found in the river. Sea trout run in late July and August. There has been a collapse in fish stocks in the 1980s and 1990s but stocks are on the rise once more since a moratorium on netting has been emplaced.

Geologically Kilmacthomas gives its name to the "Kilmacthomas Formation", which is composed of Palaeozoic deep marine metasediments and metavolcanics. Evidence of manganese nodules have been noted in the new bypass cutting recently constructed near the village.

Kilmac' is located halfway between Waterford City and the county capital; Dungarvan. West of the village are the foothills of the Comeragh mountains, while five miles to the south is the 'Copper Coast' with the beach of Bonmahon / Bunmahon (Bun Machan).
