Burma's pro-democracy leader Aung San Suu Kyi starts a five-day visit to the UK and Ireland later.
Thousands of supporters in Dublin are expected to turn out to honour the Nobel Peace Prize laureate, who will deliver an open-air address and receive the freedom of the city.
Rock star Bono and fellow aid campaigner Sir Bob Geldof will join her in a special tribute concert, where Ms Suu Kyi will be presented with Amnesty International's prestigious Ambassador of Conscience award.
She was under house arrest or in prison for 15 of the last 24 years until her release last November.
The human rights campaigner, who at the weekend accepted a Nobel Peace Prize she won while under house arrest 21 years ago, is visiting Europe for the first time since 1988.
She will fly in from the Norwegian capital of Oslo and will be met by foreign affairs minister Eamon Gilmore at Dublin airport.
Ms Suu Kyi will meet Irish president Michael D Higgins before she attends a special concert in her honour. She will also be conferred with an honorary degree from Trinity College Dublin.
Bono , Sir Bob, musician Damien Rice, the Riverdance ensemble and actress Vanessa Redgrave will be among the leading figures from the world of arts and music celebrating the event.
Hip Hop supremo and Amnesty supporter Lupe Fiasco are among the performers added to the bill.
"I feel honoured to be a part of history in celebrating Aung San Suu Kyi's long and graceful road to freedom," he said.
Ms Suu Kyi begins her visit to the UK on Tuesday, which will include a stay in Oxford, where she once studied.
