The Prince of Wales has extended his condolences to Sinn Fein leader Gerry Adams on the death of former Deputy First Minister Martin McGuinness.
Prince Charles met Mr Adams yesterday on the final day of his visit to the Republic of Ireland during a reception hosted by the British ambassador to Ireland.
Veteran Irish republican Mr Adams was among 200 guests to greet the prince and Camilla as they arrived at Glencairn House, the official residence of ambassador Robin Barnett.
It is almost 41 years since IRA bombers murdered British ambassador Christopher Ewart-Biggs at the residence.
The Prince and the Sinn Fein president shook hands and shared a joke about their dates of birth.
Charles said that they were both born in the same year - 1948 - but joked that the Sinn Fein leader was older.
The future king had earlier laid a wreath at a memorial in Glasnevin Cemetery in Dublin in memory of all those who died in the 1916 rebellion.
He and Camilla took part in a ceremony at the Necrology Wall, which bears the names of all who died in the rebellion -Irish and British, military, police and civilian.
The royal couple also took part in a ceremony at a war memorial where Victoria Cross paving stones were unveiled 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 Cpl Cunningham after he unveiled the memorial stone.
The Duchess bowed her head as she unveiled the paving stone in memory of Sgt Maj Hill Hanna.
Speaking at the end of their four-day visit to the island of Ireland, Charles said his most memorable moment was joining the acts of Remembrance.
"My wife and I were deeply moved to join acts of Remembrance," he said.
"It's so very important we are able to come together to honour the memory of so many men and women from all sides whose sacrifice shaped our shared history."
The Prince also met Taoiseach Enda Kenny at government buildings, Dublin.
As the Prince of Wales signed his name in the visitors' book, he joked: "This is just to prove I can write".
Mr Kenny showed Charles the signatures of his mother and father, Queen Elizabeth and Prince Philip.
They signed the book during their historic visit to Ireland in 2011.
