The funeral of O'Donovan Rossa is to be commemorated in Glasnevin Cemetery in Dublin tomorrow.
It is the first of the State ceremonial events of the Ireland 2016 Centenary programme.
The funeral, and the famous graveside oration by Pádraig Pearse, marked a turning point in the history of Irish independence and is credited with unifying the Republican movement.
1,500 tickets were made available to the public and a further 5,000 will be accommodated watching big screens across the road.
The event, which is being hosted by the Minister for Arts, Heritage and the Gaeltacht, Heather Humphreys, will be attended by President Michael D Higgins and Taoiseach Enda Kenny.
Those travelling to the event tomorrow are advised to use public transport, as organisers say parking will not be available and road closures will be in place.
The commemoration, will follow the proceedings of the original funeral of O'Donovan Rossa, and will culminate with a wreath laying ceremony, the firing of a volley of shots, the raising of the National Flag and the National Anthem.
Speaking on RTÉ's Morning Ireland, Chairman of the Glasnevin Trust John Green, outlined what will happen at the State ceremony tomorrow.
"The President will lead and he will lay a wreath at the graveside of Jeremiah O'Donovan Rossa and there will be a re-enactment of the oration and there will be full military honours so it will be quite a spectacle.
"We've issued 1,500 tickets to the general public, there'll be space on the other side of the road for 5,000 people to watch on a big screen," he said.
"The President will have a full guard of honour outside on the Finglas road, the traffic will be stopped, so it will be a major event."
The minister said the commemoration will follow the proceedings of the original funeral as closely as possible.
Speaking on RTÉ's Today with Keelin Shanley, Ms Humphreys said the funeral is best remembered by the graveside oration by Pearse.
Minister Humphreys said the funeral was a catalyst for the 1916 Rising: "It was a huge event at the time, tens of thousands of people lined the streets to watch the cortege.
“And again the reason for the funeral is seen to have been so influential because of the speech delivered by Pádraig Pearse because it encouraged people to get involved, and the movement swelled and plans were set afoot then for the 1916 Rising," she said.
