About Newtown Castlebyrn
The name — 'Newtown Castle Byrne' — recalls the medieval castle and settlement that once stood near present-day Blackrock. This townland sits between Blackrock and Williamstown, with residential streets that have developed over successive decades. The proximity to Blackrock village, its DART station, and the coastal amenities gives the area strong practical advantages, while the older place-name connects it to the Norman heritage of south County Dublin.
