Traffic ground to a halt in parts of Dublin Wednesday as women and abortion rights activists sang along to Cyndi Lauper's "Girls Just Want to Have Fun" and the Spice Girls' "Wannabe" during a raucous dance party on O'Connell Bridge.
After sundown, a second, separate demonstration -- also in protest against Ireland's abortion laws -- commenced, with Irish police estimating 10,000 to 12,000 people on the capital's streets.
Earlier in the day, demonstrators banged pots and pans and chanted "Same struggle same fight, women's rights are workers rights." Others carried signs saying "Get your rosaries off our ovaries" and "Yes I took a holiday for this, I'm that annoyed" as they marched through the streets of the Irish capital.
People across the country walked out of their offices and joined a day of action dubbed "Strike 4 Repeal," urging the government to hold a constitutional referendum to scrap Ireland's eighth amendment -- a measure that places the right to life of an unborn child on equal footing with the right to life of the mother.
The amendment, passed in 1983, prohibits abortion even in cases of rape, incest, or ill health of the mother, allowing it to be considered only when a woman's life is in immediate danger. There has never been a referendum put forward to repeal the amendment since it was instated.
At least nine Irish women on average traveled to England and Wales each day for abortions in 2015, according to UK government statistics.
While Ireland has voted before on the question of whether abortions should be legal, the restrictions remain in place. But a landmark ruling last June by the UN's human rights committee called on the government to reform the laws.
