Irish president Michael D Higgins laid a wreath at the burial plot of leaders of the 1916 Rising as the representatives of the country's judiciary and Defence Forces turned out for the State's annual Arbour Hill Commemoration Ceremony.
Arbour Hill is the final resting place of the seven signatories of the Proclamation of the Republic, including Padraig Pearse and James Connolly.
Those in attendance included the Taoiseach Leo Varadkar, Fianna Fail leader Micheal Martin, Sinn Fein deputy leader Michelle O'Neill and Labour Party leader Brendan Howlin.
Defence Forces chief of staff, vice admiral Mark Mellett, was also present and the celebrant of the mass before the ceremony was Bishop of Limerick, Brendan Leahy.
Members of the Seventh Infantry Battalion formed a guard of honour to the burial plot. There was a series of prayers, including some by representatives of the Church of Ireland and the Jewish and Islamic faiths.
