Carlow Castle

The ruined Norman castle on the River Barrow, in the heart of Carlow town. An independent guide to its history, how to visit, and what else to see nearby.

Plan your visit

Carlow Castle is one of the most important Anglo-Norman castles in Ireland. Today only the west wall and two of its round corner towers remain, but they still dominate the riverside in Carlow town.

Why visit?

Carlow is an easy stop for anyone travelling between Dublin and the south-east. The castle is free, close to the town centre and quick to see, so it fits neatly into a half day with the museum, the cathedral and a walk by the river.
