Castles in County Waterford

Reginald’s Tower stands at the end of the quay in Waterford city, on the corner of the Viking Triangle, and has been in continuous use for over 800 years, the oldest civic building in the country. Inside is a compact museum of Viking finds, a sword from Woodstown among them, reached by a spiral of deliberately uneven stumble steps. It is the only one here you can walk to from a city street.

Three of the others sit west along the Blackwater and its tributaries. Lismore Castle is the Duke of Devonshire’s private Irish home, so the visit is the gardens, open March to October, with contemporary sculpture set among 17th-century yew walks. Lisfinny, above the River Bride near Tallow, is a Desmond tower house on a working farm, a roadside view rather than a visit. Templemichael, on the promontory where the Glendine meets the Blackwater, is a five-storey ruin with murder holes and ogee windows, always open and free.

Dungarvan Castle falls between the two ends, over the Colligan estuary, free and by guided tour only, pairing a rare polygonal shell keep with an 18th-century barracks. The Suir entry is the thread rather than a castle, a 53 km paddling trail and a flat 21 km towpath. Lismore is the one with a season; the ruins keep no hours.

Questions people ask

Which Waterford castles can you actually go inside?
Reginald's Tower in the city has a museum inside, and Dungarvan Castle is free but guided tour only. Templemichael is an open ruin you can walk into at any time. Lismore Castle is a private home, so only the gardens open, and Lisfinny is viewed from the road.
Where in the county are they clustered?
Three sit in the west on the Blackwater and its tributaries: Lismore, Lisfinny near Tallow and Templemichael. Reginald's Tower is at the other end, on the quay in Waterford city, with Dungarvan Castle on the coast roughly between them.
When is Lismore Castle open?
The gardens open to visitors from March to October, so a winter trip means the town rather than the castle: the Burne-Jones cathedral, and the story of the Book of Lismore, sealed inside the castle wall for almost two centuries.
Can you see any of these without a car?
Reginald's Tower is on the quay in Waterford city, and Dungarvan Castle stands in Dungarvan itself, so both work on foot once you are in the town. Lisfinny and Templemichael are rural and need a drive; Lismore is a town but well west.
What castles does the Suir Blueway pass?
The Blueway threads Cahir Castle, Ormond Castle and Nash's Swiss Cottage, all upstream in Tipperary. Within Waterford it is the river approach to the city rather than a castle route, with 53 km of paddling and a flat 21 km towpath.
