The Prince of Wales and the Duchess of Cornwall will today make their historic visit to Mullaghmore, Co Sligo, where Charles' great-uncle Lord Mountbatten was killed by an IRA bomb in 1979.
It is sure to be the most poignant and emotional stop of the prince's four-day tour of Ireland.
Charles and Camilla will also attend a service of peace and reconciliation at St Columba's Church in Drumcliffe today, where they will see the final resting place of WB Yeats.
The couple are additionally due to attend a civic reception featuring performances of Irish poetry and music. And Charles will visit the Institute of Technology in Sligo.
A trip to Sligo Races will round off the second day of the royal visit.
The couple will come to Northern Ireland tomorrow, where engagements include a reception and a concert featuring a selection of local performers at Hillsborough Castle.
They will make a trip to the beautiful Mount Stewart House and gardens and while there will mark the completion of a three-year restoration programme.
And they will also visit Corrymeela, Northern Ireland's oldest peace and reconciliation centre, which celebrates its 50th anniversary this year and was previously visited by the prince.
While the focus yesterday was on the prince's historic handshake with Gerry Adams, Charles and Camilla enjoyed a full day of events.
The royal couple were welcomed to Galway by Tanaiste Joan Burton and went to a marquee party at the city's university, which was attended by 150 guests and dignitaries.
Later, Charles visited Ireland's Marine Institute in Oranmore with Taoiseach Enda Kenny.
The prince - determined to ensure happy memories of his trip - was also able to fulfil a personal lifelong dream to walk the ancient stones of the Burren landscape.
Charles spent almost an hour at the historic site and helped to build a stone wall, telling local farmers: "I've spent my life thinking about this."
The royal couple concluded the first day of their tour by joining Irish President Michael D Higgins and his wife Sabina for a private dinner at Lough Cutra Castle in south Co Galway.
On the menu was blanched Highgrove asparagus to start, followed by pan-seared halibut, with panna cotta and poached Highgrove rhubarb for dessert.
The historic building, which overlooks the picturesque Lough Cutra, provided a grand setting for the royals' final engagement.
