World Youth Day has officially begun! After years of preparation more than 200,000 of pilgrims attended the opening Mass - and are now getting ready for Pope Francis’s arrival.

Having spent a week here already the difference in atmosphere is clear wherever you go. The first week was spent training, as I’m volunteering in Kraków, and while there are 19,000 of us signed up to serve, the streets of the city were relatively quiet.

Now that couldn’t be further from the truth. Take a short walk to the Main Square and you will see nuns dancing in the street, rapping priests and hordes of people singing their national anthems.
