It’s a damp start to Sunday as worshippers make their way to Dublin’s Phoenix Park. Pope Francis is to say Mass in front of a congregation of up to 500,000.

Amid all the noise and bustle, there were moments of intense silence.
As the Pope prayed inside Knock Basilica, the crowd was hushed in prayer too.
And when he spoke, they listened intently.
Image source, ReutersAs he talked about clerical abuse and the children who were "robbed of their innocence" and "left scarred by painful memories", there was quiet.
Then, as he begged for forgiveness for this "open wound" and for the sins of scandal and betrayal, the crowd broke out into applause - agreeing with him
His time seemed very short at Knock.
Crowds got up close to Pope Francis - children on parents' shoulders; old people in wheelchairs, people in plastic ponchos and hats and mountain gear - captured by his warmth.
But those who had made the journey said it was worth it, despite the misery of the rain.
"We're here because we're Catholic and we're proud of it," said one woman.

And here's that moment in video form - the Pope's last act in Knock is signing a Mayo GAA jersey, much to the happiness of GAA fans in the county.

Fair play to this airport employee who got the Pope to sign a Mayo GAA jersey before he left Knock.
For those unaware, Mayo last won an All-Ireland in 1951 and since then have lost nine (NINE!) All-Ireland Gaelic football finals.
This Mayo fan is no doubt hoping Pope Francis can have a word with the man above...
And after a quick hour and a half in Knock, Pope Francis leaves to return to Dublin - this time with an umbrella as he gets back on the plane.

The Pope may have left Knock - his next big event is at Phoenix Park - but the pilgrims still have to get home.

Following the Pope's presentation of a golden rosary to Knock Shrine, priests from the basilica return the gesture by presenting him with a mosaic of the apparition of Mary that appeared at Knock in 1879.
That's the last action of the Pope at Knock - with that he's back off to Ireland West Airport where he'll fly back to Dublin for this afternoon's Mass in Phoenix Park.
Now the Pope is leading the crowd in the Angelus, a devotional Catholic prayer recited in memory of the incarnation of Jesus.
After the prayer, the Pope offers a "special greeting to the men and women in this country who are in prison".
He adds: "I especially thank those who wrote to me upon learning that I would visit Ireland. I assure you and your families of my closeness in prayer."

It's just as wet and grey in Dublin. BBC Ireland correspondent Emma Vardy took this shot at Phoenix Park, where 500,000 people will attend a Mass given by Pope Francis.

Pope Francis offers a "warm greeting to the beloved people of Northern Ireland".
He adds: "Although my journey for the World Meeting of Families does not include a visit to the North, I assure you of my affection and my closeness in prayer.
"I ask Our Lady to sustain all the members of the Irish family to persevere, as brothers and sisters, in the work of reconciliation."
"With gratitude for advance of ecumenism, and the significant growth of friendship and cooperation between the Christian communities, I pray that all Christ's followers will support the continuing efforts to advance the peace process and to build a harmonious and just society for today's children."
At Knock Shrine, the Pope again refers to clerical abuse, an issue that featured prominently in Dublin on Saturday.
"None of us can fail to be moved by the stories of young people who suffered abuse, were robbed of their innocence and left scarred by painful memories," he says.
"This open wound challenges us to be firm and decisive in the pursuit of truth and justice. I beg the Lord's forgiveness for these sins and for the scandal and betrayal felt by so many others in God's family.
"I ask our Blessed Mother to intercede for the healing of the survivors and to confirm every member of our Christian family in the resolve never again to permit these situations to occur."
The Pope presented a golden rosary to the shrine at Knock as a gift a short time ago.
He tells the crowd: "I know how important the tradition of the family rosary has been in this country.
"Who can tell how many hearts, of fathers, mothers and children alike, have drawn comfort and strength over the years from meditating on Our Lady's participation in the joyful, luminous, sorrowful and glorious mysteries of Christ's life."
