This is a suburb of Dublin (and quite possibly many other places, there are at least another two places in Ireland of the same name). It has a DART station and a famous boys school notable for it's rugby prowess.

Blackrock is on the coast and is home to two shopping centres (thats a mall for the american audience), they are both small. It's a pleasant enough place, but has no attractions of note. A comfortable place to live, close enough to the city and far enough away as well.
