This is one of the Church’s most popular feast days, especially in Rome. The feast is on June 29th and will be celebrated with fireworks at Castel Sant Angelo beginning at 9:30 p.m. The feast is also celebrated with the ancient tradition of floral designs laid out in the Piazza Pio XII in front of Saint Peter’s Basilica made of salt crystals and colored sawdust. The two displays will depict the Sistine Chapel and the other one will show Saints Peter and Paul. A third picture, made up entirely of flowers, will be to honor the Pope and Saint Francis of Assisi.
