From Catholic News Agency:
For the past 500 years, the Vatican has celebrated the solemnity of Sts. Peter and Paul with a bang with a spectacular fireworks show influenced by Michelangelo and Gian Lorenzo Bernini.
While many associate fireworks with the Fourth of July, the Vatican had already been celebrating this week with fireworks for nearly 300 years at the time when Americans were signing the Declaration of Independence in 1776.
