There were many such elegantly choreographed moments in this whistle-stop visit to the Vatican, a city state where every corner could be a postcard, creaking under the weight of its own history and architectural splendour.
In the Sistine Chapel the Catholic and Anglican choirs literally sang from the same hymn sheet. The images of harmony and unity were there in abundance. Once hostile churches were now the closest friends.
Surrounded by Renaissance masterpieces, this was a meeting in one of the great cradles of Western civilisation. A lover of art, music and religion, this must have been a big occasion for King Charles.
But actually later in the day there seemed to be a more intense moment, something that gave the King and Queen a chance to pause for more private prayer and reflection.
At the church of St Paul Outside the Walls they walked down some steps to the tomb of St Paul, one of Christ’s apostles. It was like walking down to the roots of Christianity. They waited there a moment and there were some prayers recited.
The King and Queen, who had switched to a white outfit after wearing black to meet the Pope, walked back up the main body of the church, where another congregation were waiting. Maybe they could have done with a few more minutes in such a simple and sacred place.
But they returned to the huge and gorgeously embellished basilica above. Even by the epic standards of churches in Rome, this was remarkably massive, with choirs once again to fill the operatically high ceilings.
