Italy

On Easter Day in Italy, the Pope presides over a very large Mass Service in St Peter's Square in the Vatican City. The service is a place of Pilgrimage to Catholics and is broadcast on Radio and T.V. all over the world.
In the Palm Sunday services and celebrations, Olive Branches are often used instead of Palm leaves.
At the start of Lent, there is a big Mardi Gras festival in Venice.
