Papal visit: Answers to the most frequently asked questions
The waiting is nearly over.
It will be the first papal visit to Ireland in almost four decades, since Pope John Paul II came in 1979.
Ahead of the weekend's events, BBC News NI's Mark Simpson answers all the essential questions about the upcoming papal trip.
Where can I see the Pope?
If you don't have a ticket for the main events, your best bet is the centre of Dublin on Saturday afternoon. He will be travelling down O'Connell Street in the popemobile just after 16:00 BST, then travelling along Dame Street.
Croke Park in Dublin on Saturday evening and Phoenix Park in the city for a Papal Mass on Sunday afternoon. But all the tickets have gone.
No, he is going to the Knock Shrine in County Mayo on Sunday morning but again that is a ticketed event, and again they have all been snapped up.
The Catholic Church in Ireland asked the Vatican to include a cross-border trip but they politely refused. The fact that there is political deadlock at Stormont may have been a big factor. With no first and deputy first ministers to meet the Pope, it would have been diplomatically awkward.
If the trip to Dublin goes well, pressure will grow for a specific visit to Belfast or Armagh in the near future ... if Stormont returns.
Once. In 1980 he came for about a month to study English.
Not good at all. He is fluent in Italian, and coming from Argentina his native tongue is Spanish.
81.
Two days. 32 hours to be exact. He arrives on Saturday morning and leaves on Sunday evening.
Yes, but the Vatican has not said when and where. Whatever happens, it is likely to be private. No cameras. We will probably only find out about it after it happens.
He will certainly say something. It is the first papal visit to Ireland since the abuse scandal broke. Recent revelations about the widespread abuse by priests in Pennsylvania in the United States have ensured the issue cannot be avoided.
Campaigners for victims of abuse want to hear more than an apology. They want to know what action the Pope is going to take. The first opportunity for him to speak about the issue will be at a state reception at Dublin Castle at lunchtime on Saturday.
Yes, wherever the Pope goes, demonstrators say they will not be far away. The main protest is at Dublin's Garden of Remembrance on Sunday afternoon at the same time as the Papal Mass at Phoenix Park.
Some people snapped up the free tickets to papal events with no intention of attending. It was a form of protest to try to reduce the crowds. It is not clear how widespread the tactic was, and whether it will have an impact.
Ian Paisley's old party, the DUP, also received an invitation to Dublin Castle, but current leader Arlene Foster turned it down. Ulster Unionist Party (UUP) leader Robin Swann also said he was double-booked that day, but unlike the DUP, he is sending a representative, Robbie Butler, who is an assembly member for Lagan Valley.
An estimated 35 million euros (£31m).
This is not a formal state visit. He is coming to attend the World Meeting of Families, a global event for Catholics held every three years.
A total of 1,200 from 31 different countries.
The Catholic Church no longer enjoys the place in society that it once held in many countries, especially Ireland, but global fascination with the Pope remains.
In a word, enormously. There has been a seismic shift on social issues. Politically, church and state have gone through a separation. Economically, Ireland has been transformed since 1979. Oh, and in Dublin pubs, a pint of Guinness is no longer 50p.
The last census, carried out in 2016, showed that more than three quarters of the population still describe themselves as Catholic. The rate of attendance at religious services also remains relatively high, compared to other European nations with large Catholic populations.
It is estimated that there will be about 80,000 at Croke Park, 45,000 in Knock and 500,000 at Phoenix Park.
Around 4,000 servers will be deployed, each responsible for groups of 1,000 people.
Mixed. Pilgrims are advised to prepare for rain, especially on Sunday.
The crowds are expected to get close to him. But at the main events, selfie sticks have been banned for safety reasons.
