Blackrock (An Charraig Dhubh in Irish) is a suburb of the city of Dublin, in County Dublin, Ireland. It is situated 3 km north of Dún Laoghaire. Blackrock has service industries and computer programming industries. Blackrock gets its name from the Black Rocks, which were located off shore in the shallow waters in the vicinity of Blackrock baths. At low tide, the remnants of these rocks may be seen opposite the north end of Idrone Terrace. These sandy shores were popular for bathing and the area's popularity as a resort peaked in 18th Century. Roque’s map of 1757 indicated that there were separate bathing places for men and women, the men’s bathing place is now buried in Blackrock Park (since the land between the shore and the offshore railway was reclaimed) and the women’s bathing place was in the vicinity of Blackrock baths. Numerous fine houses including Frescati, Lios an Uisce and Carysfort (some of which survive today) were built at this time in the vicinity of Blackrock and commanded fine sea views. A village known, as Newtown on the Strand was located between Blackrock and Seapoint until the 18th Century.
