Hayley has spent a day in the Vatican City - it's a state in Rome, in Italy, and it's where the Pope lives.
This is St Peter's Square in the centre of the Vatican City. Lots of people from all over the world come here to visit the Pope and hear his advice.
Hayley grabbed a rooftop view of the square, which is surrounded by columns and statues.
The top of St Peter's Square has 140 statues of Catholic saints.
There's also a huge church called St. Peter's Basilica in the square.
