A flag raising ceremony is taking place at Dublin Castle today
The first events will be held today to kick off the Ireland 2016 Centenary Programme.
The state programme will begin with a flag raising ceremony at Dublin Castle. Among those attending are the President, the Taoiseach, Minister Heather Humphreys and the Lord Mayor of Dublin.
The Defence Forces will read a roll of honour of those volunteers who lost their lives during the 1916 Rising, followed by a raising of the three flags which were flown on O'Connell St in Easter 1916 - the Irish Citizens Army Flag, the Irish Republican flag and the national flag.
Minister Heather Humphreys says later, a special concert will be held in the Convention Centre to mark the beginning of the centenary year.
