About Williamstown

A townland between Blackrock and Dún Laoghaire, Williamstown sits along the residential streets that connect the two larger centres. The area benefits from proximity to both Blackrock DART station and the Monkstown Road corridor, with housing from various periods giving the streets a mixed character. The coastal amenities of Seapoint and Salthill are within walking distance, and the area maintains the settled, residential quality typical of DLR's inner suburbs.
