The majority of residential high-rise buildings in the Republic of Ireland were concentrated in the suburb of Ballymun, Dublin. The Ballymun Flats were built between 1966 and 1969: seven 15-story towers, nineteen 8-story blocks and ten 4-story blocks.[1] These were the "seven towers" referred to in the U2 song "Running to Stand Still".[citation needed] They have since been demolished.
