The Forty Foot is a famous sea swimming spot in Ireland’s capital city of Dublin. For hundreds of years, only men had the privilege of bathing in its deep, icy waters – naked if they chose.

That was until one day in the summer of 1974, when a group of women decided to plot an invasion.

At a time when Irish women couldn’t even access contraception, why did this group of hardy feminists decide to fight this particular battle for equality?

Rosie Blunt speaks to poet, writer, women’s rights activist, and swimmer Mary Dorcey.
