Update - 5pm: Prince Charles and Gerry Adams have met at the site where the IRA killed a British ambassador in the 70s.
At an official function in Glencairn the two shook hands, with the Prince offering commiserations on the death of Martin McGuinness.
In 1976 the IRA set off a bomb at the site that killed an ambassador and a young civil servant.
After the meeting Gerry Adams spoke of the need for reconciliation.
He said: "The history's the history and it's really, really important, but the future hasn't been written and we need to write the future
"Particularly in these Brexit days, it needs to be a history that's based upon the best that we can get for all the people on this island."
Earlier: The Prince of Wales and Duchess of Cornwall have visited the grave of Michael Collins as part of a ceremony at a war memorial in Dublin on the final day of their tour of Ireland.
Charles and Camilla arrived at the Cross of Sacrifice in Glasnevin Cemetery for their first engagement of the day.
They attended the unveiling of Victoria Cross paving stones in memory of four Irish-born soldiers - Corporal John Cunningham, Company Sergeant Major Robert Hill Hanna, Lieutenant Frederick Maurice Watson Harvey and Private Michael James O'Rourke.
The soldiers were awarded the Victoria Cross in 1917.
Charles paused at the paving stone of Corporal Cunningham after he unveiled the memorial stone.
The Duchess bowed her head as she unveiled the paving stone in memory of Sergeant Major Hill Hanna.
Prince Charles and Arts Minister Heather Humphreys then laid wreaths at the Cross of Sacrifice.
This is the final day of the royal couple's four-day visit to the island of Ireland.
In one of his last engagements of the day, the Prince of Wales will meet with Taoiseach Enda Kenny.
The royal couple also took part in a ceremony at a memorial marking the centenary of the 1916 Easter Rising.
The short ceremony was held at the Necrology Wall, which bears the names of all who died in the rebellion, Irish and British, military, police and civilian.
Charles and Ms Humpreys laid wreaths at the wall.
A minute's silence was followed by a piper's lament.
The decision to include the names of all who had died was a cause of controversy last year and in April the wall was vandalised.
During a tour of the cemetery the royal couple paused to look at the graves of Eamon de Valera, Michael Collins and Maud Gonne, major figures in Irish nationalism.
They also stopped at the grave of James Joyce's parents.
