Guy Fawkes Night is annually held on November 5. This day is sometimes known as Bonfire Night and marks the anniversary of the discovery of a plot organized by Catholic conspirators to blow up the Houses of Parliament in London in 1605. Many Catholics are more restrained in their celebration of this day. Many people light bonfires and set off fireworks. Some light small bonfires in their own gardens, while others light larger ones in a communal space. In some towns and cities, the municipality organizes a bonfire and professional firework display in a park.
