On 20 July 1974 a group of women invaded the Forty Foot bathing place at Sandycove, Co Dublin, by "land, sea and air". The bathing place, made famous by James Joyce in Ulysses, had been exclusively male until then and the women were greeted with sexist abuse and male nudity, according to one of the participants, veteran journalist and campaigner Nell McCafferty.
Note that I took the information from the Irish Times. Wikipedia has the protest occurring on 24th July 1974 rather than 20th. I'd trust the IT over Wikipedia.
@bullivant One man said "Miss, I'm going in in my carcass in a minute," and one of the women replied, "That's all right, I work in the morgue."
@bullivant Nell McCafferty is a national treasure and one that we don't make nearly enough of. What a woman.
