The United Nations flag is to fly in Leinster House to mark Ireland's new role on the UN Security Council which begins tomorrow.
Mark Daly, the Cathaoirleach of the Seanad, confirmed the UN flag would fly at the home of the Irish Parliament for the duration of the country's two-year term on the Security Council.
He said both the Irish flag and the UN flag are symbols of peace and the initiative acknowledges the fact that every day since 1958 Irish men women from the Defence Forces have been involved in peacekeeping duties.
The Ceann Comhairle of the Dáil, Sean Ó Fearghaíl, said the Oireachtas would use the next two years to strengthen close links with international partners.
He added that much work must be done in the areas of gender equality, environmental sustainability and the need for a fairer distribution of the world's resources.
Ireland campaigned on the themes of partnership, empathy and independence as part of a successful effort earlier this year to secure one of the ten non-permanent seats on the Security Council.
Since joining the UN in December 1955, Ireland has previously served on the UN Security Council three times - in 1962, 1981-82, and in 2001-2002.
